 ## Working with `TestSuites`
 
-TestSuites are Nit files that define a set of TestCases for a particular module.
+TestSuites are Nit modules that define a set of TestCases.
 
-The test suite must be called `test_` followed by the name of the module to test.
-So for the module `foo.nit` the test suite will be called `test_foo.nit`.
+A test suite is a module that uses the annotation `is test_suite`.
+
+It is common that a test suite focuses on testing a single module.
+In this case, the name of the test_suite is often `test_foo.nit` where `foo.nit` is the tested module.
 
 The structure of a test suite is the following:
 
 ~~~~
 # test suite for module `foo`
-module test_foo
+module test_foo is test_suite

+import test_suite
 import foo # can be intrude to test private things
