When testing your code on a real target with tools such as Tessy or testIDEA, which use winIDEA's functionality, it is important to ensure that the tests are prepared properly. One of the main prepositions is that the test application works correctly on the target. Otherwise, the tool may report an error, crash suddenly, or some similar issue could happen while running the tests.
1. Build a new test application for your target.
2. Test this application in winIDEA and correct it if necessary, until you are able to manually debug it.
3. Check in winIDEA that the test application works according to your test requirements.
Usually, a good sign that the application can be used for testing is that it reaches at least the main function on the device (core) where you want to do the testing.
Often building a new test application for testing on a real target, requires an already working application which the test tool then reuses. In such case, you can start with an example application from the target device vendor, or a winIDEA Example Workspace, and then adjust it if needed so it works with winIDEA according to this solution.
