Manual and Automation Testing Methodology
Software Testing has lot of challenges both in manual as well as in automation. Generally in manual testing scenario, developers pass through the build to test team assuming the responsible test team or tester will pick the build and will come to ask what the build is about? This is the case in organizations not following so-called ‘processes’. Tester is the middleman between developing team and the customers, handling the pressure from both the sides.
So here we go with the top challenges in software testing and assurance
- Testing the complete application
Is it possible? There are millions of test combinations. It’s not possible to test each and every combination both in manual as well as in automation testing. If you try all these combinations you will never ship the product.
- Misunderstanding of company processes
Some times you just don’t pay proper attention what the company-defined processes are and these are for what purposes. There are some myths in testers that they should only go with company processes even these processes are not applicable for their current testing scenario. This results in incomplete and inappropriate application testing.
- Relationship with developers
Big challenge. Requires very skilled tester to handle this relation positively and even by completing the work in testers way. There are simply hundreds of excuses developers or testers can make when they are not agreeing with some points. For this tester also requires good communication, troubleshooting and analyzing skill.
- Regression testing
When project goes on expanding the regression testing work simply becomes uncontrolled. Pressure to handle the current functionality changes, previous working functionality checks and bug tracking.
- Lack of skilled testers
This can be called this as ‘wrong management decision’ while selecting or training testers for their project task in hand. These unskilled fellows may add more chaos than simplifying the testing work. This results into incomplete, insufficient and ad-hoc testing throughout the testing life cycle.
- Testing always under time constraint
Hey tester, we want to ship this product by this weekend, are you ready for completion? When this order comes from boss, tester simply focuses on task completion and not on the test coverage and quality of work. There is huge list of tasks that you need to complete within specified time. This includes writing, executing, automating and reviewing the test cases.
- Which tests to execute first?
If you are facing the challenge stated in point no 6, then how will you take decision which test cases should be executed and with what priority? Which tests are important over others? This requires good experience to work under pressure.
- Understanding the requirements
Some times testers are responsible for communicating with customers for understanding the requirements. What if tester fails to understand the requirements? Will he be able to test the application properly? Definitely Not! Testers require good listening and understanding capabilities.
- Automation testing
Many sub challenges – Should automate the testing work? Till what level automation should be done? Do you have sufficient and skilled resources for automation? Is time permissible for automating the test cases? Decision of automation or manual testing will need to address the pros and cons of each process.
- Decision to stop the testing
When to stop testing? Very difficult decision. Requires core judgment of testing processes and importance of each process. Also requires ‘on the fly’ decision ability.
- One test team under multiple projects
Challenging to keep track of each task. Communication challenges. Many times results in failure of one or both the projects.
- Reuse of Test scripts
Application development methods are changing rapidly, making it difficult to manage the test tools and test scripts. Test script migration or reuse is very essential but difficult task.
- Testers focusing on finding easy bugs
If organization is rewarding testers based on number of bugs (very bad approach to judge testers performance) then some testers only concentrate on finding easy bugs those don’t require deep understanding and testing. A hard or subtle bug remains unnoticed in such testing approach.
- To cope with attrition
Increasing salaries and benefits making many employees leave the company at very short career intervals. Managements are facing hard problems to cope with attrition rate. Challenges – New testers require project training from the beginning, complex projects are difficult to understand, delay in shipping date!
