# Deprecations and incoming changes

This page documents current deprecations and upcoming planned changes
inside Catch2. The difference between these is that a deprecated feature
will be removed, while a planned change to a feature means that the
feature will behave differently, but will still be present. Obviously,
either of these is a breaking change, and thus will not happen until
at least the next major release.


### `ParseAndAddCatchTests.cmake`

The CMake/CTest integration using `ParseAndAddCatchTests.cmake` is deprecated,
as it can be replaced by `Catch.cmake` that provides the function
`catch_discover_tests` to get tests directly from a CMake target via the
command line interface instead of parsing C++ code with regular expressions.


### `CATCH_CONFIG_BAZEL_SUPPORT`

Catch2 supports writing the Bazel JUnit XML output file when it is aware
that is within a bazel testing environment. Originally there was no way
to accurately probe the environment for this information so the flag
`CATCH_CONFIG_BAZEL_SUPPORT` was added. This now deprecated. Bazel has now had a change
where it will export `BAZEL_TEST=1` for purposes like the above. Catch2
will now instead inspect the environment instead of relying on build configuration.

### `IEventLister::skipTest( TestCaseInfo const& testInfo )`

This event (including implementations in derived classes such as `ReporterBase`)
is deprecated and will be removed in the next major release. It is currently
invoked for all test cases that are not going to be executed due to the test run
being aborted (when using `--abort` or `--abortx`). It is however
**NOT** invoked for test cases that are [explicitly skipped using the `SKIP`
macro](skipping-passing-failing.md#top).
