server, tap the Proxy button, tap On , and set the server’s address
and port. Otherwise, continue to the next step.
Return Code - Functions as pass/fail test criteria with focus on the
return code value of a specified server or URL.
Select a return code from the list of available return codes. If your
selected return code value matches the actual return code value,
the test will pass.
HTML Must Contain - Functions as pass/fail test criteria with focus
on the presence of a text string on a specified server or URL. For
example, this criteria can be used to ensure that the expected
page is being tested versus an intermediate portal.
To construct a text string, enter a word or several words with
exact spacing. When specifying several words, the expectation is
that these must be located consecutively at the source. The test
will pass if the text string is found. If the string is not found, the
test will fail with the return code: HTML did not contain expected
content.
HTML Must Not Contain - Functions as pass/fail test criteria with
focus on the absence of a text string on a specified server or URL.
To construct a text string, enter a word or several words with
exact spacing. When specifying several words, the expectation is
that these will be located consecutively at the source. The test will
pass if the text string is not found. If the string is found, the test
will fail with the return code: HTML did contain expected content.
How it Works
When you execute an HTTP test, the analyzer:

Contacts the DNS server to resolve the target’s name (if a URL
was specified rather than an IP address)

Runs a ping test concurrently with the HTTP Test

Establishes a TCP connection and attempts to get the web
page.

Checks for any user-specified test criteria
