How to pause your script in Selenium untill your AutoIt script is completed?

Question

I want Selenium to wait until and unless an AutoIt script is completed.

Right now whats happening is when I run the TestNG.xml file it runs all the @Test Priority wise and within 5 sec the TestNg output console shows all the @Test are passed. While my AutoIt scripts are still running in parallel in the background.

The code is as follows:

@Test (priority=1)
public void CreateNew() throws Exception
{       
    Runtime.getRuntime().exec("exeFiles\\CreateNew.exe");       
}

@Test (priority=2)
public void OpenaFile() throws Exception
{
        Runtime.getRuntime().exec("exeFiles\\OpenaFile.exe");
}

The AutoIt code is as follows:

createnew()

Func createnew()
    Sleep(2000)
    Run("Mspaint.exe")
    WinWaitActive("Untitled - Paint")
    Send("!f")
    Sleep(1000)
    Send("n")
    Sleep(2000)
    WinClose("Untitled - Paint")
EndFunc   ;==>createnew

Simpler solution is try a waitFor() on your process, this waits until the process exits.

@Test (priority=1)
public void CreateNew() throws Exception
{       
    Process process = Runtime.getRuntime().exec("exeFiles\\CreateNew.exe");
    process.waitFor();
    Integer result = process.exitValue();
    Assert.AssertEquals(0, result) 
}

Now you can add an exit code to the AutoIt script to communicate that it passed or failed. Read about exit codes here: https://www.autoitscript.com/autoit3/docs/keywords/Exit.htm

Otherwise try something like this:

• In your Java/Selenium code create a temparory lockfile
• Start Autoit.exe
• In your Java/Selenium code write a loop to check if lockfile still exists
• Last step in the AutoIt code removes the lockfile
• If the lockfile doesnt exist break out of loop and continue with the next code

Some considerations:

• Add a timeout to your loop in case the AutoIt script does not clean up the lockfile.
• Add a timestamp and testname to the lockfiles name (e.g. testname_timestamp.lck) so that you can run tests in parallel
• Clean all lockfiles when starting a testsuite

My answer borrows from Paul answer

@Test (priority=1)
public void CreateNew() throws Exception
{       
Process p = Runtime.getRuntime().exec("exeFiles\\CreateNew.exe");
p.waitFor();       
}

@Test (priority=2, dependsOnMethods={"CreateNew"})
public void OpenaFile() throws Exception
{
    Runtime.getRuntime().exec("exeFiles\\OpenaFile.exe");
}

By adding the wait onto the process it will wait for it to end.
