Top 7 Automated Regression Testing Best Practices

After you have identified the right tool for the project, optimize the QA process by following these regression testing automation best practices:

  1. Plan your QA strategy:  Build adequate time into the product lifecycle for testing, decide where QA fits into the process, and consider available resources. E.g., will every user story be tested? What kind of testing strategy will be used?
  2. Identify the test cases to automate:  Test cases that can benefit most from automation are repetitive, needed for multiple builds, hard to perform manually, susceptible to human errors, using multiple data sets, or time-consuming when tested manually.
  3. Test early and often:  Bugs caught early in the development process will have less impact on the project. They are cheaper and faster to fix than those discovered later during production or deployment.
  4. Integrate development and QA teams:  Automation and development teams should be working together seamlessly to reduce churn, minimize miscommunications, and increase the efficiency of the entire development cycle.
  5.  Create quality test data:  Use external data to make automated tests reusable and easy to maintain. To add testing scenarios, you’d simply extend the files with new data so you don’t have to edit the actual test script.
  6. Create tests that are resistant to UI changes:  Set up the tests such that they don’t rely on location coordinates to find objects by providing unique names for the controls. This allows you to create stable test scripts that won’t break due to UI changes.
  7. Coordinate development and QA:  Often times, testing can be done most effectively when conducted one sprint behind the development cycle.  Without such a lag, the code could be too fluid for effective testing and changes could break the automation.


Regression testing automation is essential for today’s fast-paced software deployment processes. It helps shorten the development cycles and reduce the time to market, allowing you to respond to user demands in a nimble manner.

To maximize the effectiveness of your testing process, it’s important to select a regression testing automation tool that meets your project requirements while allowing you to manage the entire QA lifecycle seamlessly.

Mobile Testing

Differences Between Testing Web And Mobile Apps

Functional testing of a system application, for example, a company’s network is different from testing a mobile application with thousands, if not millions, of users. Testing mobile applications involve testing many configurations and therefore taking several steps. It is vital to test your mobile app before launching it in the market. This can determine the success or failure of app development. In this article, we discuss the differences in testing mobile and web app.

We found that the contrast is mainly in different requirements, testing methods and the necessary tools.

The distinction between mobile and web application testing

  1. One of the most obvious differences is that mobile apps are designed for more users, more diverse devices than web apps.

    Although the differences between these two categories of computers are diminishing as more and more web applications become available in mobile formats, the complexity of mobile applications is constantly increasing with the complexity of the functions that mobile devices must support. The mobile application can work on multiple devices, including a smartphone, tablet, locking system or fitness tracker.

  2. Web browsers have been created stationary.

    While mobile applications must always perform computing functions on the go, web applications typically focus on desktop operations or fixed handheld with common functionality of Wi-Fi router, cursor, and mouse that is less involved in mobile applications. When testing web applications move to test mobile applications, the task is consistently expanded. Testing mobile applications should address several different functions in relation to several different environments. For your quality Android app, you should contact mobile app development companies to hire dedicated developers.

    Increasing user interest and attachment to mobile devices has led Quality Assurance (QA) to check applications for: 

    • constant communication
    • notification management
    • multi-platform sync 

    Moreover, more important than goals, objectives, and planning is the client. Thus, software testing is a task of coordinating and ensuring the level of functionality of mobile devices which will take into account customer requirements and preferences.

Technical challenges

Differences between mobile and web testing:

  1. Storage limitations (RAM).

    The RAM of many mobile devices is still less than 4 GB as well as relatively small 16 GB SSD. This creates severe limitations for RAM and storage capacity for testing, especially with regard to the enormous amount of memory and storage available to any modern web browser. In addition, services such as advertising platforms can seriously slow down your mobile browser, so transferring your web application to your phone or tablet can be difficult.

  2. Different interactions for different users.

    Interactions for computers and laptops have been stabilized for over 30 years – the mouse and keyboard are the standards for everything from working on Facebook to flash games. This constitutes the features of web application testing.

    The problem with mobile applications lies in a wide range of sensory actions – scrolling, pulling, voice capabilities (Siri and Google Now). Innovations on specific devices such as an audio set for iPhone or the Samsung headsets that use hand wave gestures add complexity to testing iOS and Android apps.

  3. Individual application types.

    The desktop web application is developed in HTML, CSS and JavaScript with some options depending on which platform the developer wants to use. Mobile applications are not that simple. They can be created as native Java or Objective-C applications, or hybrid. It is very important that a roadmap is developed for the platform to manage all types of testing.

  4. Behavior with and without the internet.

    A web application running on a Mac or PC will be useless without an Internet connection. This is the same for the mobile web application. However, a native or hybrid mobile application may have autonomous functions. Some games can be played without connection, and document editors can also save functionality in flight mode. You need to check how mobile apps behave when switching between connections or using unstable networks. This will help to test android applications, as well as iOS and web applications with higher quality.

    Of course, there is some overlap between web and mobile apps. Many mobile applications are partly related to web applications, and testers follow some common test patterns in a flexible development cycle. Availability of test management software is a key building block since you formulate a common testing strategy and pay attention to incorporating a wide range of workflows, resources, and possible problems associated with both mobile and web applications. For your quality Android app, you should contact mobile app development companies to hire dedicated developers.

Types of testing

It is important to note that manual testing, like automated testing, plays an important role for QA. A tool can save a lot of time and facilitate the process, but not all test processes will do without human participation.

Automated testing is used for:

  • module and library testing
  • UI / UX matching
  • API

Do not forget about testing web application security. It provides a comfortable work for customers and eliminates the processing of bugs after the release of applications.

Testing your Android mobile app is a key factor in order to get a great product. Top mobile app development companies should be attentive to any details and understand the importance of proper functioning of both web and mobile applications. They can help you test android applications or iOS at a high level. For your quality Android app, you should contact mobile app development companies to hire dedicated developers.

SaaS Testing: Basics and How Codeless Automated Testing Helps

SaaS or Software as a Service model is increasingly becoming popular. Thanks to its features like – quick deployment, reduced dependency on internal systems, an increase in availability, reliability of resource and most importantly low upfront costs, it serves as the best choice. However, looking at the flip side, the companies are under immense pressure to release new features at a fast pace. Adapting agile methodology for development and testing has helped the businesses, but has also come with the challenges – the need to deliver quality software. So, what could be done? How can you assure the quality of the software yet make a quick delivery?


Codeless Automated testing for SaaS-based web apps

We all know how crucial is to test any software, but with a SaaS-based application there are numerous challenges that makes testing of utmost importance. So let’s take a glance to the challenges of SaaS Application and how codeless testing could help overcome them –

Serial #Requirements of a SaaS applicationWhy is it importantSolution By Codeless Test Automation
1Frequent Updates and UI Validation
  •  Live Updates are smooth

  •  Ensuring compatibility, security, and performance of API’s when they handshake with other third-party application.
  • It possible to test the integration of the system with other interfaces or APIs
5Cross Browser functionality
  • SaaS Application need to be browser compatible and certify the minimum number of version it can support that browser, that’s where SaaS testing comes handy
  •  Certifies the compatibility with different browsers and the minimum version it would run successfully.
  • It assists in certifying the browsers, the SaaS product is compatible and the required version is supported.

As an entrepreneur, if you are looking to reduce the testing efforts, test automation could be beneficial. It not only reduces the time-to-market but could also help you with providing accurate results. For building the test automation framework, test automation strategy in-house, here is the quick approach and best practices that could help you –

Test Automation Approach for SaaS Products

An efficient automation is one reduces manual effort, improves test coverage, reliability and provides a positive ROI. Hence while formalizing a test automation framework, fundamentally for a SaaS product, you should keep in mind the features of SaaS –

Record and Play Approach

The most basic test automation approach offers convenience, low implementation cost and easy to be deployed. However, it does not provide flexibility and maintaining a record and play tool when manual intervention is required could be a costly affair in the long run.

Data-Driven Approach

The approach is best suited when a significant amount of data is to be tested under different combinations. It involves some scripting, and hence team should be skilled enough to check data output under various conditions.

Keyword-Driven Approach

A testing approach that could be expanded to various platforms, applications and environments. It suits for large/small data sets and projects of long/short duration. However initial implementation cost is one of the major pitfalls of this approach.

Hybrid Keyword Approach

The most sophisticated test approach that is long-lasting, flexible, provides you with ample checkpoints, sustainable and comes with an ability to integrate with external objects. But again, the initial implementation cost is enormous, and during initial months you may not witness a positive ROI. Hybrid keyword approach is a long-term test automation strategy and may not be the right choice for short-lived and straightforward projects.

Best Practices for Testing SaaS Products

  • Make sure to set aside resources and time to measure the performance of the SaaS application.
  • Get a clear understanding of the requirement and “How it needs to be tested.” Just for example does SaaS product needs integration with any other application? Or Would it work under different environments?
  • With frequent release, set aside some time for exploratory testing in every release that helps in getting new test cases and bugs
  • Make sure to perform upgrade testing, data migration testing with frequent upgrades and changes of SaaS application
  • Ensure the security, stability and quality of the SaaS application when connected to third party APIs
  • Set an estimate to your test automation efforts. Just for example once you guys have decided on the approach, how much time do you think it would need to write one test script? How much time does it need to execute it? It would help in comparing the estimated and actual efforts, thereby re-aligning your test strategy and leading to a higher ROI.
  • The user base is quite crucial for a SaaS application, hence make sure to have room to scale up in case it is needed.
  • Set up a plan for disaster recovery to ensure your users are not in a hung state in case of discontinuance of service.
  • Ensure Reliability testing in your release cycle for smooth deployment of code onto live site.

While founders know, the prime motive of building a SaaS application is that it is customer focussed. Have you thought they are also getting the quality? SaaS testing is a comprehensive test solution that includes Functional, Security, Load, Performance, Cross-Browser, and compliance testing. Codeless Test Automation of SaaS test scripts shortens the test cycle helping in frequent upgrades and release of SaaS application.
