Game Testing

 there are 7 types of game testing techniques:

1. Functionality testing: Hunts for generic problems within the game or graphics and user interface. Issues like freezing, crashing and progressions blockages are common in this area.

2. Combinatorial Testing: This is used in early game stages and helps navigate through game necessities. it analysis input and output of the game so you can get clear combinations and outcomes. 

3.Ad Hoc Testing: aka "general testing" that is done in a random section of the game and does not require documentation of the errors found.

4. Compatibility Testing:  This tests if there is any defects and functionality issues in the final product and its essential requirements such as software, hardware and graphics. used to test if the screen size is optimized for different sizes and for different handsets/consoles.

5. Clean Room and Tree Testing: Consistency and reliability. Clean room testing is used to produce a product with no errors. tree testing is used to help organize the test cases and make exact choices best suitable to fix a the set of code 

6. Regression testing: Game testing is rechecked to analyze the working of previous functions and that new ones work well and to see if new bugs have appeared.

7. Performance Testing: This is to determine the overall performance under real time scenarios and load and use this information to finalize the various performance of the game and its components
