Question

Hi
I’d like to get some ideas and feedback as to how you would tackle the task of parsing this file.
I basically need the name and status of each subtests between “Starting Test” and “Finished Test”
The issue is that sometimes there is no “Finished” and it goes straight to start due to a test crash.

I started my script going line by line trying to tackle all the scenarios but the logic started to get complex and convoluted so I couldn’t help but think there must be a smarter approach to this.
Any ideas, code, pseudocode would be greatly appreciated.

    myfile.log
****Starting test of test1
Message: Total Tests: 5
Log 23w4arg
Log 3958300
Message: PASS : test1SubTest1(): Pass
Log 23w4arg

    <?php

$file = "log.txt";
$fh = fopen($file, "r");
$contents = fread($fh, filesize($file));
$lines = explode("\n", $contents);
foreach($lines as $l) {
        $startStr = "****Starting test of ";
        $l = trim($l);
        if(stristr($l, $startStr)) {
                $curTest = str_replace($startStr, "", $l);
                echo "$curTest info:\n";
        }
        if(substr($l, 0, 7)=='Message') {
                if(stristr($l, "Total Tests")) {
                        echo "$l\n";
                }
                else {
                        // Test result
                        $infoArr = explode(":", $l);
                        echo "$infoArr[2] completed with result $infoArr[1]\n";
                }
        }

}

?>


Produces:
test1 info:
Message: Total Tests: 5
 test1SubTest1() completed with result  PASS 
 test1SubTest2() completed with result  PASS 
 test1SubTest3() completed with result  FAIL
 test1SubTest4() completed with result  PASS 
 test1SubTest5() completed with result  PASS 
 4 passed, 1 failed, 0 skipped completed with result  Totals
test2 info:
Message: Total Tests: 3
 test2SubTest1() completed with result  PASS 
 test2SubTest2() completed with result  PASS 
test3 info:
 test3SubTest1() completed with result  PASS 
 test3SubTest2() completed with result  PASS 
 test3SubTest3() completed with result  FAIL
 2 passed, 0 failed, 0 skipped completed with result  Totals

I would add in some checking for failed tests and stuff, but this should be enough to get you started.
