robotframework-expects 0.4.0

How to use this:

1. Install from PyPI pip install robotframework-expects

2. Add library to RF test suite in training mode Library Expects TRAINING

3. Catch a value ${VALUE}= .. from your SUT in your test

4. Add expect block to the test Should be as expected ${VALUE}

5. Run your test robot yoursuite.robot -> generates a file yoursuite_expects.json

6. Change library to normal mode Library Expects (remove TRAINING)

7. Run your tests

Improving expectations

There are three ways to improve expectations:

1. Run a test multiple times in TRAINING mode to gain better validation model from multiple example runs.

2. Run a test in INTERACTIVE mode to stop execution on failing Should be as expected. Then explore and make a better validation model.

3. Modifying _expects.json by hand.

When expectations change

If your system changes in a way that old expectations should not be used, just remove _expects.json file and switch library to TRAINING mode. Then run your test to record new expectations.
