## How do I run global setup/teardown only if tests will be run?
|
|
|
|
|
|
|
|
|
|
Write a custom [event listener](event-listeners.md#top) and place the
|
|
|
|
|
global setup/teardown code into the `testRun*` events.

## How do I clean up global state between running different tests?
|
|
|
|
|
|
|
|
|
|
Write a custom [event listener](event-listeners.md#top) and place the
|
|
|
|
|
cleanup code into either `testCase*` or `testCasePartial*` events,
|
|
|
|
|
depending on how often the cleanup needs to happen.

## Why cannot I derive from the built-in reporters?
|
|
|
|
|
|
|
|
|
|
They are not made to be overriden, in that we do not attempt to maintain
|
|
|
|
|
a consistent internal state if a member function is overriden, and by
|
|
|
|
|
forbidding users from using them as a base class, we can refactor them
|
|
|
|
|
as needed later.

## What is Catch2's ABI stability policy?
|
|
|
|
|
|
|
|
|
|
Catch2 provides no ABI stability guarantees whatsoever. Catch2 provides
|
|
|
|
|
rich C++ interface, and trying to freeze its ABI would take a lot of
|
|
|
|
|
pointless work.
|
|
|
|
|
|
|
|
|
|
Catch2 is not designed to be distributed as dynamic library, and you
|
|
|
|
|
should really be able to compile everything with the same compiler binary.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## What is Catch2's API stability policy?
|
|
|
|
|
|
|
|
|
|
Catch2 follows [semver](https://semver.org/) to the best of our ability.
|
|
|
|
|
This means that we will not knowingly make backwards-incompatible changes
|
|
|
|
|
without incrementing the major version number.
