Testing

Writing unit, integration, acceptance, regression, performance, etc. tests in Rust.

Writing unit-, integration-, etc. tests should be an integral part of the development work, but in my experience in many organizations it is more like an afterthought. Sometimes relegated to a separate team or separate department.

Some people put a lot of emphasize on the separation between unit-, integration-, and acceptance testing. They are all part of the larger group called functional testing. I think it is primarily a question of scope. They all have the same equation:

Fixture + Input = Expected Output + Bugs

In this series of articles we are going to cover how one could write tests in Rust.

• In the series about the Rocket web development framework each example in each article comes with its tests.

• Show standard output and standard error in tests

• Test command line applications

• There is a nice collection of types of testing.
