HOW TO USE THIS TOOL

  - Ocft is a testing tool for resource agents. Instead of the policy of HA,
    it mainly concerns whether resource agents run correct locally. It can 
    design types of complicated environments to test the reliability of 
    resource agents. Precisely, it is to display whether resource agents can 
    return to correct or expected value. The advantage of the tool provides 
    us with competence to design conditions which can be recorded or reproduced. 
    Hence it is useful to debuggers.

* Components
    ** Test case generator (/usr/sbin/ocft)
      - Turning configuration files of test case to executable scripts.

    ** Configuration file  ($CONFIGS_DIR/)
      - Every configuration file directs only one resource agent and share the same 
        name with resource agent but contains more test cases.

    ** The testing script  ($CASES_DIR/)
      - After the generator reads configuration files and generates many testing 
        scripts and the script is underway, the test begins.

* How to customize the environment of testing
  - Ocft designs the running conditions through two ways, one is changing the 
    environment variables of resource agents (it is the interface left by OCF itself), 
    the other is modifying the OS environment of resource agents, such as altering 
    the permission of some key file or IP address of the machine.

* How to test
  - Firstly, you need to sketch the all complex and uncommon environments against 
    a certain resource agent and keep in mind what consequences may be caused by 
    these uncommon environments. 
    Secondly, write the designed conditions and foreknown consequences into 
    configuration files, and then run the generator to translate the test case to 
    executable scripts. 
    Finally, you need running these scripts to observe the output and learn 
    the running status of each test case, which will compares the predicated result 
    with the actual one. If they differ, you will be able to find the bugs of the 
    resource agent.
  - All of the output with test will be recorded into the log files, you can find them
    in $CASES_DIR/logs.
