Is there any design pattern for large if else statement?

I have a series of test that need to run one after another. The previous programmer wrote a giant if else. I've simpified down to a global bool variable that is check at the start of each procedure. Here is the some code snippet.

  // Run Luminance Test
        RunLuminanceTest(ref failureCode, ref failureDescription);

        //Run MSR check
        RunMsrCheck(ref failureDescription, ref failureCodes, ref failureCode);

        //Run Firmware check
        RunFirmwareCheck(ref failureDescription, ref failureCodes, ref failureCode);

        //Check Monitor power up
        RunMonitorPowerUpCheck(ref failureCodes, ref failureCode);

        // Run Power Check
        RunPowerCheck(ref failureCodes, ref failureCode);

        //Check Video Abnormality
        CheckVideoAbnormality(ref failureCodes, ref failureCode);

        // Vmi Check
        RunVmiCheck(ref failureCodes, ref failureCode);

This is really ugly and prone to have bugs. Is there a design pattern that can I can implemented to make it easy to read and debug? The program is written in C#/Winform.

edit: sorry for the confusing. Prasad telkikar's link is what I'm looking for. I am looking for a design pattern that can replace a giant if else statement.
