Additional Tools & Formats

If your tool isn't supported yet, don't hesitate to contact us; we continuously add support for new formats.

# Which Coverage Tool To Use

The following lists coverage tools that we recommend you use to obtain code coverage for your tests. These are tools that we have used successfully together with our customers in the past. However, other tools may work as well.

Third-Party Tools

Please note that we are not the vendor of most of these tools and thus cannot directly support you in case you face problems with their setup. Please contact the appropriate vendor.

We will, however, of course help you to setup the upload of their coverage report files to Teamscale and to use Test Gap analysis in Teamscale.
