5 Reasons Why It’s Worth Writing Test Cases

Some people wonder why spending time on writing test cases if the app’s functionality is already known. This opinion is fairly takes place as there is always a great work to do and few opportunities to write extended test cases. So why should you?

These are 5 reasons for this.

  1. I’ve probably already covered all regression test cases, but it’s unlikely with your new functional ones. However, you’ll need to write those because big chances are there will be more testers having to check this functionality again. So you have to document thoroughly how the feature should be tested to let future testers run your test case when they need to.
  2. Depending on the level of formality, environments within a SDLC model will normally produce some kind of design requirements for new functionality. As you aren’t familiar with it, you’ll have to build test cases to be taken all the way through validating the functionality’s been properly implemented. Similarly, you’ll build them to assess how you’ve addresses and tested all the product requirements.
  3. Theoretically, you are to automate as many manual tests as possible. To build automated scripts, you already need to have detailed manual test cases so that to know well what to script.
  4. In-depth test cases also make a great means of learning the product for newly employed testers. By executing a set of regression test cases they’ll get a fairly good hands-on experience about the product and your quality assurance company’s test management processes without much help from the others.
  5. Lastly, it’s better to write test cases as soon as you don’t want to be considered a person fearing to give away his precious knowledge. If you this, better drop. You can’t be the only person responsible for the project QA all the time, that’s why you should contribute your knowledge into the training of new testers as well as the successive nature of your QA company’s testing processes and success as a whole.
