The above error states that PHPUnit is not installed in you WAMP stack.
The easiest method to install it is using PEAR. Try following this method to install PHPUnit with PEAR :
Go to the directory where PHP is located. Typically, this is \bin\php\php5.3.8
We’ll call this path “PHP’s location”
Download “go-pear.phar” from this location:
pear.php.net/go-pear.phar
Create a folder “pear” in your PHP’s location
Put the downloaded “go-pear.phar” file in this location.
Open a command prompt with administrative privilege. For this, click
on start menu, type “cmd” – you can see the cmd.exe icon.
Right-click on this icon and click “Run as administrator”
Cmd.exe will open. Go to the direcotry of your PHP’s location, by
typing “cd” command. For example, my wamp is located in “D:\wamp”,
so I write following command:
D:
cd wamp\bin\php\php5.3.8
Now run the downloaded file, by typing:
php .\pear\go-pear.phar
Installation will begin! During installation, you’ll need to respond
to some prompts, just hit enter/press “Y” when necessary.
After installing, double-click and instal “PEAR_ENV.reg” found in
your PHP’s location.
Optionally, you can add your PHP’s location in your PATH variable.
After you can install PHPUnit like this :
Open a command-prompt, go to PHP’s location using cd, and type:
pear channel-discover components.ez.no
pear channel-discover pear.phpunit.de
pear channel-discover pear.symfony-project.com
pear install --alldeps phpunit/PHPUnit
Type phpunit –version to confirm installation.
That should install PHPUnit, and now you may try
phpunit DbTest.php
Hopefully, it should work.
