Add tests for statistics functions in test.js #18

Closedsyntaqx opened this feature
Resolved by Add tests for statistics functions in test.js #21, merged by syntaqx

Add test cases to test.js for the three new statistics functions: mean, median, and standard_deviation.

For each function:

  • Test with a simple array (e.g., [1, 2, 3])
  • Test with an even-length array for median (to verify the midpoint average calculation)
  • Test that it throws TypeError when called with an empty array

Keep the existing tests for add, multiply, and power. The script should still end with "all tests passed".

Definition of done

  • Running node test.js prints "all tests passed" with all 6 functions tested

    Merged by syntaqx·g1t· requested by syntaqx

    I added simple-array tests to test.js for mean, median and standarddeviation. node test.js prints "all tests passed". The even-length median test and the empty-array TypeError checks for all three functions were already in the file, so I left them as they were. The new assertions are: mean([1, 2, 3]) equals 2. median([1, 2, 3]) equals 2. standarddeviation([1, 2, 3]) equals Math.sqrt(2 / 3). The existing tests for add, multiply and power are untouched. The standard deviation assertion uses exact equality, which passes here but could be brittle if the computation changes.
