How to stop Robot Framework test execution if first testcase FAIL?

Question

As shown in below robot file, I have three testcases. I want to stop the test execution, if TESTCASE1 fails. TESTCASE2 should be executed only if TESTCASE1 passes.

Answer 1

There are multiple ways to get the job done, each appropriate for different situations.

--exitonfailure

The command line option --exitonfailure aborts the test run after any testcase fails, unless it is marked noncritical.

Fatal Error

You might only want to abort if exactly TESTCASE1 fails. The Fatal Error keyword exist just for this purpose:

TESTCASE1
    ${passed}=  Run Keyword And Return Status  boot device
    Run Keyword If  not ${passed}  Fatal Error

If this seems clunky to you, you can throw fatal errors directly from Python/Java.

Suite Setup

These tools will get the job done, and are appropriate in some cases. Although in the asker's case, I observe:

• The first testcase must pass for any other tests to run.
• It runs a keyword called boot device.

To me that is not a testcase. That is a setup. If you need a setup to run once before a suite of testcases, you should specify it as a Suite Setup.

***Settings***
    Suite Setup    boot device
