问题
I have some jest tests and I can determine the coverage with
jest --coverage
Also see Code coverage for Jest
I automatically execute the tests on a build server (gitlab runner) and want that my tests fail if the coverage is below a certain limit.
In python there is a flag --cov-fail-under that can be used with pytest, e.g.
pytest --cov src --cov-fail-under=90 --cov-report=term
Unfortunately, I could not find a corresponding option for jest.
=>What is the recommended way to check the total coverage?
Should I write some extra script to evaluate the generated json coverage file or is there an easier solution like a specific reporter to use?

Not listed under CLI-Options, but there is coverageThreshold, which can be used in package.json or within an extra jest configuration file:
