Testing Your Code

The Test[] method in the VisionScript standard library provides a method for testing your code. The standard library contains methods that you can use in your code but must be imported before use.

To test a program, first import the Test module:

Import["Test"]

To write a test, use the Test[] method.

In the following script, we test that the number of cats in a provided image is greater than 3:

Detect["./cats.jpg"]
Count[]
Test[Count[] > 3]

Tests are counted in two global values:

• PassedTests: The number of tests that have passed.
• FailedTests: The number of tests that have failed.

To read the number of passed and failed tests, use the PassedTests and FailedTests methods:

Say["Passed tests:"]
Say[PassedTests[]]

Say["Failed tests:"]
Say[FailedTests[]]
