Quality Professionals-Visual Testing

In this article, we will learn about a type of software testing known as Visual Testing. We will investigate the various subjects surrounding this testing approach and how we at Q-Pros adopt its various methods to guarantee excellent results. What is Visual testing?"Visual Testing" is observing an application’s visible output while monitoring for visual bugs and assessing the output in comparison to what is expected by demand. Examining an application's interface is done during the production period by developers, and later end-to-end users (a person who intend to use a product) will seal the deal with the product in the final stages. The front-end developer’s main concern is to make sure that an application looks good on all browsers and devices with no obvious defects in terms of appearance. HTML and CSS as well as JS are interchangeable and can behave differently from one platform to another. This causes the risk of errors that not only affect appearance but also the functionality. Considering such concerns, Visual testing is highly demanded by clients as a major step in QA (Quality Assurance).The distinct value of Visual TestingTesting your application's script and making sure each input delivers an expected output on a basic level is not enough. Changes regarding layout and interface could occur due to a lack of compatibility. Certain elements such as height, width, background color, font style, font size, and position within screen coordinates could change from one platform to another. This change is a result of different operating systems using various rendering methods.Developers need to have their code written in a way that includes all previous versions of script input. Tools such as Babel could ease up the process by re-writing a code to make sure it could be rendered by all browsers in the same way. Cross-browser testing is a different approach with similar objectives. It includes other aspects than visual ones and focuses on how an application behaves in various browsers, making sure an application is operating based on business requirements and has achieved the desired quality level on all available browsers.Manual Visual Testing Vs Automatic Visual Testing Manual Visual Testing Manual Visual Testing involves testing an application by sheer observation through usage and excavating any notes or anomalies that might stick out. This form of testing is becoming less popular because it is time-consuming. To put it in perspective, testing an application "manually" will require testing it on all available browsers, in all operating systems, and taking into consideration, available devices and different screen configurations and screen displays. This will take a lot of time to accomplish, and it will open room for false readings.Automated Visual Testing In Automated Visual Testing, developers use tools and software to automate the test process and compare visual elements across different screen combinations. Automated tools such as Selenium or Appium ease the process by running the script and creating UI variations. As good as it may seem to have all screen combinations generated automatically, it still leaves the burden of testing it yourself to check for any bugs or defects. One way to make things even easier is to rely on a method called Snapshot Testing.In short, Snapshot testing creates a bitmap of multiple screen combinations and compares pixels, reporting/highlighting any unexpected changes in color hex code. By comparing each pair of pixels in combination A & combination B, a snapshot test highlighted the difference as shown in the third table. The Issue with Automated Visual Testing and The Snapshot Method: As good as it may seem, Automated Visual testing is not perfect. While companies are relying on automated means of visual testing, the need for manual observation is essential.Rendering will always cause deference – Relying on an algorithm to detect differences is almost redundant, as the algorithm will always report bugs. This is because pixels do not represent visual elements. Certain rendering activities include algorithms that create pixel differences to run a script. Encountering some differences on a UI level does not always translate to bugs – some operating systems/browsers adjust CSS codes in a way that is seen as suitable. For Example, Minor changes may occur to the text based on the browser being used.Q-ProsVisual testing is a field that co-exists with a lot of other non-functional testing methods; it is an inseparable need of QA. At Q-Pros We run scripts on various scenarios to make sure the script runs well on all available platform combinations. We rely on automated tools as well as manually checking visual elements via a team of QA experts. Request a Service ...

Amongst its many objectives, Quality assurance practices focus on investigating difficult scenarios that involve misuse of the application. We look to confirm that an application behaves as expected when an unexpected scenario occurs.Following this methodology, Q-Pros can scale up software applications and ensure top quality while discovering ways to improve the application. In this article, we will look at a testing approach called Negative Testing, and we will also look at some negative test scenarios. What is Negative Testing? Negative testing is one of two main software testing strategies (Positive and Negative). Unlike its adversary, Negative testing focuses on test cases that drift away from common use(I.e., providing improper data as input) While positive testing follows an application’s intended steps to make sure it runs as intended. Take for example an application that has a conditional insert field, what will happen if the user enters a space or a character inside an input field for numbers? Negative testing looks for ways that can challenge the application and get it outside its comfort zone to make sure it holds its ground. Some bad results might include system crashes or null outputs of no use.While performing quality tests, we must include all possible events. Our testing engineers look for the most sophisticated way of improper use to make sure the system is aquept for everything. Negative Test Case Scenarios To give you some understanding of what negative testing situations look like, here are some scenarios to clear it up some more: Data fields character limitations - To establish a stable database, most applications have a set of conditions for data entries by users.These conditions can also serve to organize personalized data on websites and assert security guidelines. An example of that would be authentication-based applications that will only allow a certain type of characters to be inserted while creating an account name or password. Number of characters - To avoid any sort of misuse, software systems would only allow a certain number of characters to be entered. This condition is essential for developers because it discredits any type of behavior that seeks to crash the system by overloading it with input. On the other hand, not adding enough characters would go against security regulations. Required data entry - So far, we looked at scenarios involving the quality and quantity of data entered, but what if the user decides not to enter data at all? Here we need to assess system deficiency when fields are left empty and make sure the system behaves well when this scenario occurs. Logged-in/Logged-out tests - Some services and lay-out options change and adapt based on account status, so if you are logged in, some options will show, and this would cause changes in the UI/UX. The objective of negative tests here is to make sure that certain combinations do not mix up and that the application remains intact. In conclusion Developers write certain “if statements” in the script of any software application. The reason those if statements are important is because this type of function would direct the user’s journey on the application and create limitations to what you can and cannot do as a user. Using Negative tests, we can check for weak points that might go unnoticed in the early phases of development or when certain updates are made. ...

mobile app testing techniques, functional testing and non functional testing, bugs in software testing

The objective of QA activities is to find and detect defects and ensure fulfillment of requirements as desired by stakeholders. We at Q-Pros put this on the top of our priorities when serving our clients. In this article, we will investigate bugs in software Testing, what are the criteria followed to report a bug, the terminology used, and why we get bugs? To start, let us look at the definition of bugs in a software system. Definition of “Bugs in Software Testing” A bug is a way to define a certain defect that is blocking an application to work as required. Finding bugs can be defined as the main objective of the entire testing process.Bugs might be caused due to several kinds of mistakes made by developers in the development phase. Types of Bugs in Software Testing Bugs are segregated into categories based on casualty as such: · Coding Error: A bug caused due to a mistake in the coding phase (Internal mistakes). · Design Error: A bug caused due to a designer’s mistake, these bugs could cause issues in functionality and behavior. · New suggestion: This type of bug is concerned with enhancement. A testing expert would suggest a change rather than a severe fix. · Documentation issue: Documentation issues could cause ambiguity and misunderstanding amongst involved developing teams. Which in turn results in bugs and defects. · Hardware problem: Bugs caused by hardware issues interfering with the application of the software. Types Of Bug Severity In order to prioritize QA efforts, we separate bugs in terms of severity. Bugs in Software Testing are defined based on effect level into the following types: · Blocker: Blocks a certain function or test to be actioned. · Critical: Causes system crash and major loss of data. · Major: Causes a huge abnormality of function. · Minor: Causes a small/minor loss of function. · Trivial: UI enhancements required. · Enhancement: A suggestion for a certain change or modification. - Using Jira as a bug-tracking tool Jira is an open-source tool that is used for bug tracking, project management, and issue tracking in manual testing. It offers services and features that include reporting, recording, and workflow. Jira is a prominent project management tool that is easy to use and works best for projects that require multiple teams and levels of involvement. Characteristics of a Valid Bug (Bug Criteria) Reporting defects can be trickier than you would think. For us to consider a bug valid for reporting, it must follow a certain criterion. First, a Bugs in Software Testing should be unique and have its own unique ID, this means that we cannot relate to more than one defect regardless of how close they are in the scope of application. Then you must consider the fact that bugs should be reproducible, meaning that more than one tester can get the same bug when following the same steps leading to that bug. Thirdly you should dedicate as much time as possible to make sure that the bug report is clear and cohesive and can be transferred from one team to another to get the issue fixed. - Read Also “Mobile App Testing Checklist for a Defect Free App” Where do Bugs come from? There are several reasons why we get bugs in Bugs in Software Testing. The top two factors of bugs immerging are: · Poor communication Communication during the development stages is highly significant and is a key factor in project management. Post-production bugs come about due to miscommunication which leads to ambiguity, meaning that there was an unclear or misunderstood transfer of information during the initial stages of requirement planning and design on what the software is required to do. · Programmer’s mistake Programmers might make mistakes during the coding phase, which will most certainly open the door to several bugs and defects. Testing experts have methods to check internally to root out the cause of a defect from the source code directly. Learn more about software testing approaches at Q-Pros and request a service via our online test request. ...

Globalization testing and localization testing are two types of tests that are incredibly important in software testing. It is vital for business owners to have their applications suited specifically for a desired market or market. And it is our role at Q-Pros as a leading testing provider to ensure that for our clients. In this article, we will investigate the differences between the two and why we perform these forms of tests. What is Globalization Testing? A type of software testing that is performed to ensure that an application is compliant with global standards and is available in multiple languages while including several features based on various regional conditions. Examples of global applications would include Google. It adjusts itself based on the user's location, ensuring a unique experience for each country. Various features will include languages, time zones, currencies, and many more. Globalization testing is done via a team of testing experts who ensure the software is set for the global market based on modern demands. This could be done while collaborating with translators and business experts who can guarantee the level of inclusivity the application would have based on clients’ requests. What is Localization Testing? A type of software testing in which the intent is to make sure the application is designed for a fixed region. This includes showing regionally relevant content and optimizing the application for a specific language. An example of a localized website is a government website, such as bundesregierung.de, which is only available in German, French, and English. It is specifically designed for German citizens and features information that is exclusively relevant to Germany. - Globalization Testing Vs Localization Testing - Globalization Testing Localization Testing A test was performed to make sure that an application could be used by various users around the globe A test is performed to make sure that the application is designed to be used eventually in a specific region It is used to validate different currencies, addresses, and mobile numbers in software It is used to validate particular currencies, addresses, and mobile numbers Takes more time to conduct Takes less time to conduct Requires higher cost to include various elements Takes a lesser cost to perform It separates the translator from the developer to guarantee independent results Testing is only done on limited levels Why is localization important? Studies have shown that localized apps generate more stable revenue, this is because region-customized applications maintain a loyal and frequent following as users become more dependent on them. Localized applications would include specific features that are adjusted for a certain country or some countries. These features are of unique design and are made to be suitable and accessible for a limited group. Why is Globalization important? To include as many users as possible, it is obvious that business owners would want to globalize their software. Globalized applications would include specific features that adjust or adhere to certain countries. These features are also compliant with cultural norms and take into consideration the difference in display and perception between regions. It is incredibly significant for companies to ensure as much usage as possible. This helps establish the strong and weak points concerning geographical areas. Future marketing analysis relies a lot on Globalization testing as it helps get a clear image of why certain applications might not perform as well in separate places.

In this article, we will get to know more about a term commonly used in the QA (Quality Assurance) world. It is associated with automated means of testing a product. Codeless testing, or codeless automated testing, provides solutions for developers and testers by ensuring everybody’s involvement in the testing process regardless of their level of technical knowledge. So, what is Codeless testing? What are the specifics of implementing codeless automated tests? And how we at Q-Pros take advantage of such practices to ensure better and more guaranteed results for our clients. What is Codeless automated testing? Codeless automated testing is a type of testing that involves no writing of code. It allows teams to automate writing tests without the need for code-writing skills. By relieving the testers from the time-consuming code/scriptwriting process required in many manual code-based tests, Codeless Automation allows for more time within the Dev-Ops cycle, accelerates the software development lifecycle (SDLC), and channels more energy toward development and innovation for developers and testers alike. Codeless vs Code-based Testing By distinguishing testing approaches based on code usage/dependency, we produce terms such as low-code, no-code, and code-based testing. These terms are regarded as frameworks adopted by testing experts based on the business needs and requirements. Some products require simple forms of testing by following the logic of use. These approaches require little-to-no-code knowledge, while other more complex forms of testing rely extensively on script knowledge. Codeless Code-based Little to no coding skill Requires strong coding skills ~ Less than an hour a test ~ 5 to 6 hours per test Relies on self-handling tools Proactive in nature Tested on web and mobile Mobile native (Appium) & desktop web (Selenium) Test scenarios are flow-based Test scenarios are page-based When to use Codeless testing? To achieve top-quality results, any organization should ensure a healthy balance of code-based & codeless testing methods. Not all tests can be done via codeless means, some tests are too complex, and unpredictable, and it would be impossible to get accurate results without a hefty use of code. Certain tests for behavior for example are difficult to test for using codeless automation methods. An application being blocked on certain devices, or cases where different results are erupting irregularly. In the QA world, tests are segregated based on objective, and by understanding the required goal of the test, one can choose a testing method that is fitting for the mission at hand. Rather than scanning all aspects of an application using one code-based methodology, relying on codeless testing first-hand regarding certain aspects saves a lot of time. Components, features, and approach. Selenium is an open-source medium used for automated testing. It provided companies with a good ROI (Return on Investment) in their projects by accelerating the testing process. While companies relied on Selenium for automated testing, Selenium offered a component that allows the recording, editing, and debugging of functional tests, called Selenium IDE (Integrated development environment). Selenium IDE recorded testing steps and later provided the option to convert these testing steps into a programming language. Basic features for Selenium IDE: Allows test case reuse via the Run command. Provides automation cross-browser testing using the Selenium SIDE runner. Supports a mix of commanding options like loops and raise asserts. Runs a specific test or a testing suite. Records scripts, which can be later accessed manually for editing. Its benefits can be extended using plug-ins (Third-party services provided by Selenium). Another highly-ranked automation tool that offers a codeless feature is Katalon Studio. It is described as simple to use with unique features. Basic features for Katalon Studio: Very minimal coding skills are required. Built-in test case libraries, project templates, and keywords. It allows for recording and playback. Used for API, desktop, and mobile. Allows for the use of plug-ins. Many other tools that are unique in features are provided for test experts to make use of. Software development companies are adding and enhancing versions of their testing applications so that they can offer faster and easier ways of testing more efficiently. These innovative tools not only benefit testing experts or developers but also provide a sense of comfort for clients looking for better results. Codeless Automation using Cloud By utilizing cloud technology, we can speed up the testing process even more. Removing the supervising human user from the process and making sure that every aspect of an application is tested. Several benefits include: Adjusting workload as needed automatically. Automation on a cloud test for scalability easily without the need for hardware. Cloud automation testing can be accessed anywhere, anytime. Security is provided by the cloud provider. Cloud automation meets robust requirements. Q-pros is a leading Quality assurance company, with years of experience, we managed to stay ahead of the curve in all state-of-the-art testing utilities.
