+FFmpeg tests
+============
+
+Tests are useful to make sure that code changes do not introduce regressions.
+
+## FATE tests
+
+FATE (FFmpeg Automated Test Environment) is the system used to test
+regressions and should be used for new changes which affect the API or
+components behavior.
+
+To run all tests, run the following command from the commandline:
+```
+make fate
+```
+
+To get the complete list of tests:
+```
+make fate-list
+```
+
+You can specify a subset of tests to run by specifying the
+corresponding element form the list with the `fate-` prefix, e.g.:
+```
+make fate-ffprobe_compact fate-ffprobe_xml
+```
+
+## FATE samples
+
+By default, FFmpeg uses only the standalone tests. To use the
+collected FATE samples, you need download and configure the tests with
+the FATE samples path.
+
+To upload or update the samples, run the command:
+```
+make fate-rsync SAMPLES=/path/to/samples
+```
+
+Then you need to setup the path where the samples are located, either
+when configuring with:
+```
+./configure --samples=path/to/fate/samples
+```
+
+or when running the tests with:
+```
+FATE_SAMPLES=path/to/fate/samples make fate
+```
