For this to work you first need to [create a user account on GitHub](https://help.github.com/articles/signing-up-for-a-new-github-account/) if you don't already have one.

$ git commit -m "Commit message 1"

Please keep in mind that the project has a Continuous Integration job to check that your new code is satisfying the

format defined in the file `.clang-format`. Use your preferred text editor, IDE or method to make sure your code is
|

properly formatted before creating the PR.
|

|

Note: You can use the script `contrib/scripts/clangFormatWholeProject.sh` to format the whole project.

|

$ make tests # Integration tests

$./bin/unit_tests # Unit tests

$ ctest

Exiv2's (new) test system is described in more detail in the [doc.md](tests/doc.md) and [writing_tests.md](tests/writing_tests.md) files, and a description of the old
