# Running Tests
|
||
|
|
|
||
|
|
In order to complete this exercise, and all of the subsequent exercises, you
|
||
|
|
will need to pass multiple tests.
|
||
|
|
|
||
|
|
## Understanding Test Results
|
||
|
|
|
||
|
|
After you have created and saved `hamming.rb`, run the test suite. You should
|
||
|
|
see output like the following:
|
||
|
|
|
||
|
|
# Running:
|
||
|
|
|
||
|
|
SSSSSSESSSSSSSSS
|
||
|
|
|
||
|
|
Finished in 0.002593s, 6170.4588 runs/s, 0.0000 assertions/s.
|
||
|
|
|
||
|
|
1) Error:
|
||
|
|
HammingTest#test_identical_strands:
|
||
|
|
NameError: uninitialized constant HammingTest::Hamming
|
||
|
|
Did you mean? HammingTest
|
||
|
|
../hamming/hamming_test.rb:9:in `test_identical_strands'
|
||
|
|
|
||
|
|
16 runs, 0 assertions, 0 failures, 1 errors, 15 skips
|
||
|
|
|
||
|
|
You have skipped tests. Run with --verbose for details.
|
||
|
|
|
||
|
|
|
||
|
|
The letters `SSSSSSESSSSSSSSS` show that there are sixteen tests altogether,
|
||
|
|
that one of them has an error (`E`), and that the rest of them are skipped (all
|
||
|
|
the `S` letters).
|
||
|
|
|
||
|
|
The tests are run in randomized order, which will cause the letters to display
|
||
|
|
in random order as well.
|
||
|
|
|
||
|
|
The goal is to have all passing tests, which will show in two places:
|
||
|
|
|
||
|
|
1. `SSSSSSESSSSSSSSS` will become a series dots: `................`,
|
||
|
|
|
||
|
|
2. The line at the bottom will read `16 runs, 0 assertions, 0 failures, 0
|
||
|
|
errors, 0 skips`.
|
||
|
|
|
||
|
|
## Passing Tests
|
||
|
|
|
||
|
|
Write enough code to change the Error to Failure, and finally to Passing.
|
||
|
|
|
||
|
|
Open `hamming_test.rb`, and find the word "skip". All but the first test start
|
||
|
|
with "skip", which tells Minitest to ignore the test. This is so that you don't
|
||
|
|
have to deal with all the failures at once.
|
||
|
|
|
||
|
|
To activate the next test, delete the "skip", or comment it out, and run the
|
||
|
|
test suite again.
|
||
|
|
|
||
|
|
## Wash, Rinse, Repeat
|
||
|
|
|
||
|
|
Delete one "skip" at a time, and make each test pass before you move to the
|
||
|
|
next one.
