A handy Python test framework (pytest) and its CI settings __python

background

Some of our formal code is written in Python, and this part of the code needs TDD, so we need to find a useful test framework. Framework Selection

Python's Test Tools encyclopedia:

Python Mainstream testing tools for horizontal comparisons

According to the following article, we decided to use the Pytest

Normal pytest installation is not covered by coverage

Pip Install Pytest

Pytest coverage requires additional installation

Pip Install Pytest-cov

At this time, the new Py.test command, which is the original Pytest command on the basis of encapsulation, new coverage features.

Example Demonstration:

Py.test test_conf2bin.py--junit-xml=test_conf2bin_report.xml--cov-report=html--cov-config=.coveragerc--cov=./

Test_conf2bin.py is the target test file –junit-xml=test_conf2bin_report.xml is the test_conf2bin_report.xml–cov-report=html that generates the JUnit format The report –COV-CONFIG=.COVERAGERC the output HTML uses the. COVERAGERC configuration file (Py.test is based on coverage.py and therefore supports coverage.py configuration files)

–cov=./this is necessary, without this, will be unable to output HTML report

. Coveragerc This file allows Py.test to implement more advanced features, as follows:

[Run]
Branch = True

[the]
include = conf2bin.py

[HTML]
directory = Python_coverage_report

[The]
Include = conf2bin.py
Because Py.test accounting for all the files in a folder, if you only need statistics conf2bin.py the coverage of this file, you can write
[HTML]
Directory = Python_coverage_report
Refers to the HTML output folder last

Pytest personal trial, indeed very good, more than the test frame with a strong
