#Iunit testing update

This way if you (or anyone else) decides to update the game, you can be confident in knowing that the update didn’t break anything that was working before. Now that you know how the game works, it’s time to write unit tests to ensure everything behaves as it should. Getting Started with the Unity Test Runner Try playing for a while, and then make sure the ship gets hit by an asteroid to see that Game Over triggers. If an asteroid hits the ship, the ship explodes and it’s game over (with the option to start again). If a laser hits an asteroid, the score will go up by one. Use the left and right arrow keys to move the spaceship left and right.

Open the Crashteroids Starter project (you can find the Download Materials button at the top or bottom of this tutorial), and open the Game scene in Assets / RW / Scenes.Ĭlick Play to get Crashteroids started, and then click the Start Game button. If any individual test in a test suite fails, the entire test suite fails. A test suite houses all unit tests related to a logical grouping of functionality (like your combat unit tests). These test names might seem long and very specific, but this is helpful.Įvery unit test you write makes up part of a test suite.

UpdateNameDoesntAllowNonLettersToBeAddedToNameįrom these test method names, you can see that you’re testing that the “unit” of work being performed by UpdateNameWithCharacter is doing what it should. UpdateNameDoesntAllowCharacterAddingToNameIfNameIsTenOrMoreCharactersInLength The names should make it clear what’s being tested: Take a look at the sample test method names below. How would you write unit tests for the UpdateNameWithCharacter method?īefore you get started with implementing these unit tests, you’ll need to think carefully about what the tests are doing, and come up with names for them. This method is testable because it does a “unit” of work.

Once those two tests pass, the code adds the character to the end of the name.

If the length of the name is ten characters or greater, it prevents the user from adding another character.

If the character is not a letter, this code exits the function early and doesn’t add the character to the string.

Public void UpdateNameWithCharacter(char: character) Your method intercepts each keystroke and adds that character to the name field as shown below: You wrote the method so there are no numbers allowed in the name, and the name can only be ten characters or less. You’ve written a method that allows the user to input a name. This might be hard to grasp before you’ve written any unit tests, so consider this example: You should design a unit test to validate that a small, logical, snippet of code performs exactly as you expect it to in a specific scenario. Exactly what makes up a “unit” varies, but the important thing to keep in mind is that a unit test should be testing exactly one ‘thing’ at a time.

:]Ī unit test is (ideally) for testing a single “unit” of code. What Is a Unit Test?īefore diving into code, it’s important to have a solid understanding of what unit testing is.
