But high code coverage value itself is not telling anything about quality of the code and tests, so we always try to improve the way we test our products. You can read about our mutation testing practices and in this article […]
What is Mutation Testing? Mutations are automatically seeded into your code Tests are run If your tests fail -> the mutation is killed pass -> the mutation lived The quality of your test suite can be measured by the percentage of mutations lived. In other words, your application code is automatically modified. When the production […]
