Samples

The subfolders here match the example/pattern tag from the slides. Unless otherwise stated, you can chdir to the respective folders below and run go test -v

Test composition

samples/ex1 --- Hello World through tests

samples/ex2 --- Table driven tests & subtests

You can also try running individual tests:

go test -v -run=TestAdderUsingTable
go test -v -run=TestAdderUsingSubtests
go test -v -run=TestAdderUsingSubtests/Positive

samples/ex3/test_normal --- Tests for UnsafeCounter

samples/ex3/test_suite --- Suite

In addition to -v, you can also add -d and -w switches. -d shows the Type and address of the instances under test per-test. -w shows before and after wrapper functions at Suite level and per-test

Fixtures

samples/F1 --- No code here. The pattern is used in ex3

samples/F2 --- Idempotent teardowns

Run go test -v -d for debug output.

Additionally, the code comments mention changes that can be made to simulate errors and obesrve behavior in the output

samples/F3 --- Fixture that returns a teardown func

The code has commented t.Fatalf lines which can be uncommented to induce errors in both SETUP and TEARDOWN

samples/F4 and samples/F5

These are variants with minor changes.

samples/G1 --- Gotcha 1

Lines that demonstrate behavior are printed directly. Just run go test -v

samples/G1 --- Gotcha 2

Lines that demonstrate behavior are printed directly. Just run go test -v
