each test independent of the others? can we test preview or save if edit isn't working?

• edit
  • logged in & not logged in, click the "edit" link at the top & "type" the "action=edit" url & click section edit & type section edit url
    • verify the textarea exists
    • verify the textarea contents are correct
    • verify that typing works
• save
  • in edit mode, click the "Save page" button
  • verify that the page saves
    • we're now NOT in edit mode
    • the contents of the page are what we expect
• preview
  • in edit mode, click the "Show preview" button
  • the page shows both the contents of the page in html AND the textarea we're editing

Next Actions

• need to carefully think through edit tests to make sure they cannot pass when they shouldn't - all 8 tests now pass!
• CFLN issue very interesting - I'm writing this $sectionOne="==first section==" .chr(13).chr(10). "test text in page $testPage $timestamp"; and then getting this from the test runner:

Failed asserting that 
<string:==first section== test text in page AboutUsTest.com 1173799512> 
contains "==first section==
test text in page AboutUsTest.com 1173799512".

Done

• created files basic_wiki_functions_acceptance_test.sh & BasicWikiFunctionsTest.php
• testEditLinkWholePageIP() & testEditLinkWholePageLogin() both call editLinkWholePage() which does the actual work - the only difference is the login one logs in
• testEditLinkSectionIP() & testEditLinkSectionLogin() both call editLinkSection() - same as above
• basic structure of the file is complete now with 8 tests in two categories, logged in & IP; calling 4 functions in two categories, whole page or section; calling 2 functions in two categories, edit link or type edit URL; call DoTest(), so it's something like this
  • doTest
    • editLink
      • editLinkWholePage
        • IP
        • logged in
      • editLinkSection
        • IP
        • logged in
    • editURL
      • editURLWholePage
        • IP
        • logged in
      • editURLSection
        • IP
        • logged in

Notes

• carriage return line feed issue
  • linux uses LF only, mac uses CR only, win uses CRLF [1]
  • What do I do about this?
  • What happens if we use CRLF ( chr(13).chr(10) )?
• whole page text, not just one section
• look for more duplication in code

getText

public function getText($locator)
{
return $this->selenium->getText($locator);
}

public function getText($locator)
{
return $this->getString("getText", array($locator));
}

private function getString($verb, $args = array())
{
try {
$result = $this->doCommand($verb, $args);
} catch (Testing_Selenium_Exception $e) {
return $e;
}
return substr($result, 3);
}

private function doCommand($verb, $args = array())
{
$url = sprintf('http://%s:%s/selenium-server/driver/?cmd=%s', $this->host, $this->port, urlencode($verb));
for ($i = 0; $i sessionId)) {
$url .= sprintf('&%s=%s', 'sessionId', $this->sessionId);
}
if ($this->driver == 'curl') {
$response = $this->useCurl($verb, $args, $url);
} else {
$response = $this->useNative($verb, $args, $url);
}
if (!preg_match('/^OK/', $response)) {
throw new Testing_Selenium_Exception('The Response of the Selenium RC is invalid: ' . $response);
}
return $response;
}

useCurl

   private function useCurl($verb, $args, $url)
   {
       if (!function_exists('curl_init')) {
           throw new Testing_Selenium_Exception('cannot use curl exntensions. chosse or "native"');
       }
       if (!$ch = curl_init($url)) {
           throw new Testing_Selenium_Exception('Unable to setup curl');
       }
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       $result = curl_exec($ch);
       if (($errno = curl_errno($ch)) != 0) {
           echo("curl_errno: " . $errno);
           throw new Testing_Selenium_Exception('Curl returned non-null errno ' . $errno . ':' . curl_error($ch));
       }
       curl_close($ch);
       return $result;
   }

The $url here is the selenium server url. curl_exc is calling that url. Next to check is what selenium server does with getText as the verb in the $url.

getText docs?

look what I found: http://wiki.openqa.org/display/SEL/Selenium+Core+API+Documentation+Standard

Selenium.prototype.getText = function(locator) {
  /**
   * Get the (trimmed) text of a form element.
   * @param locator an element locator specifying the element whose text
   *   we'll extract
   * @return string the (trimmed) text of the element
   */
  var element = this.page().findElement(locator);
  return getText(element).trim();
};

and

getText, which is defined as follows in selenium-api.js:

Selenium.prototype.getText = function(locator) {
var element = this.page().findElement(locator);
return getText(element).trim();
};

yep, line 1154 in selenium-api.js [2]

	Selenium.prototype.getText = function(locator) {
	    /**
	   * Gets the text of an element. This works for any element that contains
	   * text. This command uses either the textContent (Mozilla-like browsers) or
	   * the innerText (IE-like browsers) of the element, which is the rendered
	   * text shown to the user.
	   *
	   * @param locator an element locator
	   * @return string the text of the element

	   var element = this.browserbot.findElement(locator);
	   return getText(element).trim();
	};

assertElementContainsText

   public function assertElementContainsText($locator, $text)
   {
       $this->assertContains($text, $this->getText($locator));
   }

/r/n, /r, & /n

Very strange.

• Mediawiki doesn't care if I put /r or /n or /r/n into the wiki text, which is good, of course.
• If I put in /r/n or /r or /n and then change /r/n to /n and then /r to " " and /n to " " in my expected text, my tests pass as long as I don't have /r/r
• if I do have /r/r then that gets replaced in my expected test with two spaces, while in the getText output, there's only one space - I really need to look at docommand() to see why/how these end of line characters are being replaced/stripped
