[Dev] Test script with concurrent threads

Thu May 24 11:32:38 PDT 2007

Well, that is a step forward.

runTest() is now being called inside the thread. That is good.  
The second parameter to start_new_thread() is a tuple that should contain the arguments for the method you pass on. In your code, you are sending (i,), which means you are sending one parameter (the value of variable i).

Now, since in the original code you were executing "test.runTest()" and it was actually executing, that means runTest does not need any argument!  Any class method always receives the "self" parameter and any other parameter you pass.  If you pass (i,), the thread will call test.runTest(self, i). The error then makes sense, it says it is receiving 2 arguments but was expecting 1. 

If what I suspect is true, then your call should be "thread.start_new_thread( test.runTest, ())". note the empty parenthesis in the second argument.

Second try! Good Luck!

Thank you William for your response.

I've executed without the parenthesis, like thread.start_new_thread( test.runTest, (i,)),  but now I'm getting the following error:

Traceback (innermost last):

  (no code object) at line 0

TypeError: runTest() too many arguments; expected 1 got 2

Any idea?

Thanks,

Filipa

Hi Filipa.

Sorry for the late response. Since this is the third post without answer, I thought I take a look althought I'm not a Python expert.

I found something in the line "thread.start_new_thread( test.runTest(), (i,))" but I'm not sure. 
As I understand from what I just read in internet, the start_new_thread() method receives two parameters: a method and a tuple with arguments to pass to the method. 

That means, the first parameter is the method you want to call. But, you don't need to call it, you just need to pass the method. In the line above, you are actually executing test.runTest() due to the parenthesis!
I think the line should be: "thread.start_new_thread( test.runTest, (i,))", note there are no parenthesis in runTest. 
With your line, you are first executing runTest(), and the result is passed to start_new_thread().  If runTest() returns a method, then the call is correct, but I think that is not your case. 

Please remove the parenthesis from runTest and try it, then let me know if it works. Again, I'm not an expert, so good luck.

Subject: [Dev] Test script with concurrent threads

 Hi!

I'm still trying to execute a test script with concurrent threads, but the threads are being executed in a sequential order instead. Can anyone tell me how can put the threads executing concurrently?

I really need some help!

This is the code I'm executing:

    numThread = 3
    numThreadPerBlocks = 5 
    fimThread = 0
    tinicio = Date().time 

    while (i < numThread):
        x = 0
        if (numThread - i < numThreadPerBlocks):
            numThreadPerBlocks = numThread - i

        while (x < numThreadPerBlocks): 
                print "Start thread ", i 
                test = Portal5( 1, 'console file ', 0, '20.|300|301|302|303|304|307|401|403|408|41.', ' log.xml', 5, 5, 5, 1, 1, 'Portal5', 1 ) 
                test.setUp()
                thread.start_new_thread( test.runTest(), (i,))
                x += 1
                i += 1  
                time.sleep(10)

        time.sleep (40)
        print "Stop between blocks" 

    while (fimThread < i):
        time.sleep(1)

This is my text output:

Start thread  0

Portal5: Initialize 

test: setUp

test: runTest

Request step: 1,  <http://www1.asd.pt/PortalWeb/content/> http://www1.asd.pt/PortalWeb/content/

..

Thanks in advance, 

Filipa
