Matchers.py assert_text_present

[stevenerat]

Using 0.63, I found that the locator block in Matchers's assert_text_present fails for me because it is not prefixed with self.

Code:
e = driver.find_element_by_tag_name('body')
assert text in e.text

Error:
File "/Library/Python/2.7/site-packages/py.saunter-0.63-py2.7.egg/saunter/matchers.py", line 345, in assert_text_present
e = driver.find_element_by_tag_name('body')
NameError: global name 'driver' is not defined

Fixing that to be ...
e = self.driver.find_element_by_tag_name('body')

... resolved that error, but something was odd in the timing because my test was passing yet my WebUI threw a handled exception in a popup, perhaps something timing related, but reproducible every time in pysaunter, but not when manually testing.

So, I modified the locator usage (and added some handling to raise an assertion error) with the following, and this works for me every time.

    if isinstance(self.driver, tailored.remotecontrol.RemoteControl):
        assert self.driver.is_text_present(text)
    else:
        try:
            locator = ("xpath=//*[contains(text(), '%s')]") % text
            self.driver.find_element_by_locator(locator)
            return True
        except:
            if len(msg) == 0:
                raise AssertionError('Text "%s" was not found.' % text)
            else:
                raise AssertionError('Text "%s" was not found.  %s' % (text,msg))
