+# Test Documentation: 
+
+The test framework pytest is used to run tests. 
+
+Test files are identified by prefixing `test_` to the file names. Such files 
+will be collected automatically by the Pytest framework.
+
+To run the test type the following at the command prompt:
+
+> pytest
+
+
+## Test specifications
+
+The first part of the `test_xxx.any` can include specifications for the test framework. 
+Things such as define and part statements or certain errors to ignore.
+
+The specification section must be commented with //. The test will execute that part of 
+the file as python code. So the code must be valid python code except for the leading //
+
+
+### Specifying define statements:
+
+The following specifications are supported:
+
+* define 
+* path
+* expected_errors
+* ignore_errors 
+* expect_errors
+
+
+// Note. Since this test example include a main file from another
+// application it also alters the ANYBODY_PATH_MAINFILEDIR and 
+// ANYBODY_PATH_MAINFILE preprocessor flags. 
+//
+// If these flags are important to the model they must be mocked by the
+// test framework. This can be done by adding the following test directives
+// to the top of the test file.
+
+
+## 
+
+//path = {'ANYBODY_PATH_MAINFILEDIR':'../Application/Examples/StandingModel',
+//        'ANYBODY_PATH_MAINFILE':'../Application/Examples/StandingModel/StandingModel.Main.any' }
+//
