The PHP Assertion Unit Framework (phpAssertUnit) is a unit testing framework based on assertions which helps PHP developers test their code. Failing assertions about the program state are tracked in a Reporter window of a DOM-compliant browser such as IE5+, Mozilla, Netscape 6+, etc. The reporting of failures or warning messages does not disturb the running script, allowing easy Web GUI testing.

Sputnik is easy to install on shared hosting without root accounts.
