Comparison of Python unit test frameworks Nose and pytest

The Python automated testing RobotFramework does a good job, but it is not convenient in some places. Although one of python is studious, the addition of east and east in the Robot Framework increases the learning difficulty and is not conducive to the development of automated testing. 2. RobotFramework has castrated many python functions. For example, it is difficult to nest for. At the same time, you have to look at the unit test framework of python. Unittest and doctest in the standard Python library have simple unit test functions. However, we need to test the use case tag function. An example of this tag: Our test cases can be labeled as high, some labeled as middle, some labeled as low, and you can choose to execute as high or all cases. None of these functions are supported by unittest and doctest. So we switched to the external module. From the perspective of pypi, the external unit test modules mainly include pytest and nose. Nose downloads are several times higher than pytest. On the surface, you should definitely choose Nose. In practice, it is found that Nose is not suitable for our project. See the following comparison results. In terms of documentation: The py. test documents are made into exquisite pdf documents with detailed examples. Nose documents only contain web files, and almost no instances can be found. The test shows that we have no strict requirements on this part. Both Nose and py. test can meet the requirements. Test Report: pytest is much better than Nose.
