+#### Below are the tests
+####
+#### Before each test :
+####  - increment the variable ntest
+####
+#### Run the command as the condition of an if / then /else
+####  - The command must return 0 on success
+####  - The command must return an exit code different from 0 on failure
+####  - The datafiles are stored in the same directory than the test script
+####  - The test script directory is stored in the TEST_DIR variable
+####  - If result files have to be produced they must be stored
+####    in the temporary directory (TMPDIR variable)
+####
+#### then clause is executed on success of the command
+####  - Write a success message using the log function
+####  - increment the variable success
+####
+#### else clause is executed on failure of the command
+####  - Write a failure message using the log function
+####  - increment the variable failed
