When do you use BDD?

In my opinion, BDD should be used for verifying the most important parts of the application using end-to-end tests. That probably includes starting the application and test it with Selenium or similar. BDD should also be used to verify the wanted behaviour using integration tests.

What is the disadvantage of BDD?

Why do developers not do their own testing?

One reason is that they work within one section of the application code and don’t understand how the entire application works. In other cases, developers have told me that they don’t make mistakes. And I’m not the only one who has heard this.

Is it better to do QA or developer based testing?

The current trend among software development teams is to move away from QA-based testing in favor of developer-based testing. But is that the right choice? You can find strong opinions on both sides.

According to the Standards, once the content frameworks are developed, the test developer can assemble a set of potential test items that meets the test specifications.
