1. Pytest skips test cases
During the execution of automated tests, we often have this situation: some use cases cannot be executed due to functional blockage, unrealized or environmental problems, etc. If we comment out or delete these test cases, recovery operations may be required later , then we can configure to skip these use cases.
PytestThere are two ways to skip tests in the testing framework: skipand skipif.
(1) Unconditional skipskip
skipmethod to unconditionally skip test cases.
How to use: @pytest.mark.skipMark on the test cases that need to be skipped.
(2) Conditionally skipskipif
skipifThe method is to conditionally skip the test case, and the condition is true to skip.
How to use: @pytest.mark.skipif( condition=condition for skipping , reason=reason for skipping),
Mark on test cases that need to be skipped.
- Parameters
condition: The skip condition, if it is True, skip the test, if it is False, continue to execute the test, the default is True. - Parameter
reason: The reason for skipping the label, a required parameter.
(3) practice

2. Pytest fails to retry
Pytest failure retry means that when a test script is executed, if the execution result of a test case fails, the test case is re-executed.
premise:
The pytest testing framework fails to retry and requires pytest-rerunfailuresa plugin to be downloaded.
Installation method:pip install pytest-rerunfailures
The way Pytest implements failure retry:
Method 1: Use it on the command line or in the main() function
pytest.main(['-vs','test_a.py','--reruns=2'])(This method has not been successfully implemented, and it may be a problem with your own environment)
or:
pytest -vs ./test_a.py --reruns 2 --reruns-delay 2(Can)
Indicates: retry 2 times on failure, and wait for 2 seconds before each retry.
Description:
rerunsIt is the number of reruns,reruns_delayand it is the interval time, the unit is s
Method 2: pytest.iniUse in the configuration file (recommended)
Add retry parameter in pytest.iniconfiguration fileaddoptsreruns
[pytest]
addopts = -s --reruns 2 --reruns-delay 2
testpaths = scripts
python_files = test_01.py
python_classes = Test*
python_functions = test*

Note: If the setting fails to retry 5 times, and it succeeds during the retry process, there is no need to retry all 5 times, and you need to pay attention here.
