How should I fail a test when an if condition becomes false

Question

I want a test to fail when the if condition below becomes false.

last_url = self.browser.current_url

if 'https://***/news/' in last_url:
    print("test passed")
else:
    #Test should fail if it reaches here
    print("test failed")

How can i achieve that?

Answer 1

You can use

assert 'https://***/news/' in last_url

You can try it in Python console:

>>> last_url = 'https://***/news/page.jsp'
>>> assert 'https://***/news/' in last_url
>>> last_url = 'https://***/no-news/page.jsp'
>>> assert 'https://***/news/' in last_url
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError

Answer 2

You can use self.fail(msg="…").

Answer 3

You can use Asset in this case, below is the dummy code try this. I have used Java based code here you can, you can change as the language which you are using.

int isURLMatching =0;

if 'https://***/news/' in last_url:
    print("test passed")
isURLMatching++;
Assert.assertTrue("message", isURLMatching>0);

else:
    #Test should fail if it reaches here
    print("test failed")
isURLMatching=0;
Assert.assertFalse("message", isURLMatching==0);
