  1. 1. Best Practises In Test Automation February, 2017
  2. 2. Introduction Agile development is the key to survival in today’s digital era. To meet growing user expectations, apps need to evolve fast. For implementing continuous app improvements, development teams need regular testing insights through test automation tools. In the initial stages of development, as more features are added, manual exploratory testing becomes crucial. As a product matures, complexity of an app increases. When there is a large software project with many system users, you need a continuous testing strategy to ensure that the project is on the right track. Relying solely on manual testing to execute repetitive testing steps is not only costly but also time consuming and ineffective. Automation simplifies and speeds up the testing process for large projects, making it easy to move from one build to the next, without the risk of breaking things. With automation, testing tools run the tests to ensure that the expected outcomes of the developing programs match the actual outcomes. For better accuracy and speed, test automation is crucial. It can help achieve test coverage & speed for large projects. A combination of manual testing & test automation can give a software product adequate test coverage to eliminate risks, if any. Key Merits Of Automation : ·​ ​It is useful in scenarios that require continuous delivery and continues testing. ·​ ​With automation, you can run tests faster and get results quickly. ·​ ​Faster results help development teams to implement changes faster. When To Automate Tests With automation, developers can get feedbacks faster & reduce the risk of breaking things as they progress from one build to the next. The defects can be found faster. The cost of fixing them can be reduced as well. However, before opting to automate tests, companies must factor in the need & measurable benefits of test automation. A good & simple rule would be to aim for automation of repetitive testing tasks that are prone to human error. Automation Testing is needed in the following cases:
  3. 3. 1) When the app is stable Any feature that is at least 80% stable & unchanging can be automated. Automation involves considerable investment of time & effort. A product that is not stable is likely to change functionality wise. There is no point in test automation for products that are not stable in terms of functionality. 2) When there is no manual regression testing Regression testing involves testing of unchanged parts of an application. Automation testing becomes critical for regression tests to ensure that no features break from one build to the next. As these tests are repetitive in nature, they need to be automated to save cost & time. The automation frame work for regression tests should include the option to add & update test cases. 3) When you need faster results Automation allows companies to execute repetitive & difficult tests faster. Product managers can get quick feedback & ensure that no feature is broken from one build to another. 4) When testing steps are repetitive Any static or repetitive test that is relatively unchanged in new test cycles can be considered for automation. The time saved can be devoted by testers in conducting critical exploratory testing of the product. 5) When there is huge volume of data Data driven tests that involve validation with huge volume of data and inputs are more likely to get errors when done manually. Setting up test data again & again is a major pain point. Further as & when new features are released, you have to set up the complex test data in various test environments. Uploading multiple variations of the same data is a time consuming and difficult process. Automation in these cases not only speeds up the process, but ensures better accuracy. A simple script will allow you to upload different variants of the same data & track the test easily. Challenges In Test Automation Test automation of work flows requires the help of skilled domain experts. The major roadblocks to achieving adequate automation coverage is the huge investment required for testing an app in real world conditions & the investment required for setting up a test

Best Practises InTest Automation In order for testing process to be fast & effective, product managers need to intelligently plan & execute their test automation strategy. A good rule is to not try & automate everything at once. Start with critical workflows that are crucial for your app. Individual test cases that need to be automated must be identified. The following is a list of best practices in test automation that you can adopt to make your testing process more effective: 1) Understand The App & Know What To Automate Automate features only after they have stabilized and are likely to remain unchanged. Ideally, automation scripts should be created for repetitive tests that need to be executed with each release like regression cases. Automation can cover smoke tests & build acceptance tests that are frequently performed. These kind of tests are time consuming and difficult to execute manually. The goal is to simplify repetitive tasks and make it easier for manual testers to focus on ways to improve product quality. Additionally, don’t try to automate everything as it involves considerable investment in time & resources to not only set up the framework but also maintain it. Identify critical workflows based on the risks assessed. Automate only critical workflows that don’t involve complex checking system or manual analysis. Good knowledge of your app will also help in finalizing the right tool for automation. 2) Choose The Right Automation Tool The automation tool must be compatible with the technology used by your application. Know the browsers the app supports; the language it is built on & the technology it uses. Choose a tool that is most familiar for your team, which does not incur a lot of time in learning the technology. The tool should help in execution of multiple test cases without any intervention and should generate accurate logs at the end
  7. 7. of the tests. Check if there is scope for extending the capabilities of the tool. Selection of the right tool makes the automation process easier. 3) Include Manual testing & Test Automation In Framework Good test automation begins with creation of good manual test cases. Include provision for manual testing and creation of effective test cases in the automation framework. Leverage on manual testing to create & implement effective test designs that can be automated. Each test case should be clear & less dependent on the other test cases. These test cases should be run manually to identify bugs before the creation of automation scripts & also used to finalize the workflows. Validate and remove test cases that are not compatible with the app. Listing out & testing all scenarios manually in this manner helps in identifying the actual scope of automation. 4) Create Automated Tests That Are Reusable & Maintainable A good automation framework must support changes in the tests. While creating the framework, consider the possible future modifications that may happen in the application. Adopt a process of creating modular scripts that are less dependent on one another. 5) Create Effective Test Data A well-structured test data makes it easier to create & execute automation scripts. It is also simpler to maintain & reuse high quality test data. The automation framework must be data driven & should enable input of data in various formats. This saves up time for execution of data driven tests. It also makes it easier to write automation scripts as the product matures. 6) Avoid GUI Automation The UI of an application is prone to changes during different stages of development. Further, relying on UI makes automated tests slow & increases the risk of errors. To ensure that your scripts work on future versions of the applications, make your automated tests resistant to UI changes. Avoid automating the GUI. 7) Aim For Faster Results To create & execute automation scripts faster, companies can take the support of crowd sourced testing platforms. Crowd testing platforms enables clients to access an on-demand & skilled QA team who can help attain maximum automation coverage faster. The lesser the turn around time for results, the more
  8. 8. frequently and earlier you can implement the testing process. Faster execution will enable developers to get quick feedback to find & fix all regression bugs. Conclusion Automation plays a crucial role in the success of a software development project. Adequate planning & investment in testing & automation tools can hence reduce the risk of poor app quality, reduce time to release products & improve the effectiveness of QA teams.
