Video game testers play video games before they are released to the public. Testers closely analyze the games to make sure they work properly.

Creating a video game is a group process:

• Designers work together to combine their expertise in art, technology, storytelling, sound production, and world creation.
• Programmers write the code that makes all the parts work together.
• Testers make sure everything works correctly.

When testing, testers use a methodical system to work through video games. When they find an error (bug), they report it to their supervisors or the programmers. They document the sequence used during testing so they can keep an accurate record of bugs.

When bugs are fixed, testers go back through the sequence to see if they can recreate the error. They often review the same section of a game many times trying to locate errors.

Video game testers also review games to see if they are user friendly and to make sure people will have a good experience playing the game.
