 ### Added
 
-- Added Testing using [GoogleTest](https://github.com/google/googletest). For details, please see [test/README.md](test/README.md) ([#121](https://github.com/asmaloney/libE57Format/pull/121))

 - Added `E57Exception::errorStr()` to get the error string directly. ([#128](https://github.com/asmaloney/libE57Format/pull/128))
 - {cmake} Use [ccache](https://ccache.dev/) if available. ([#129](https://github.com/asmaloney/libE57Format/pull/129))
 - {ci} Added a CI check for proper clang-formatted code. ([#125](https://github.com/asmaloney/libE57Format/pull/125))
