+# CLI tests
+
+This suite of tests is not intended to do complex integration tests, but simple
+unit-test like tests of the CLI flags. Testing allowed inputs, flag-combinations, etc.
+
+## Running all tests
+Using the `Makefile`;
+```
+make test-cli
+```
+or directly;
+```
+tests/cli/test.sh --suite "decK-cli test suite"
+```
+
+## Running a single file
+```
+tests/cli/mytestfile.test.sh
+```
+## Create a new test-file
+To create a new testfile run:
+
+```shell
+tests/cli/test.sh --create tests/cli/mytestfile "decK-cli test suite"
+```
+
+instructions will be in the generated file.
