# crunchtestdemo

Demo usage of httptest to capture mocks from the crunch API.

In this 

[commit](https://github.com/gergness/crunchtestdemo/commit/cce311a552ee45baf4cffe5d3e99426339570bb3), 

we go from a (simple) working but untested package,

to one that uses httptest to have mock tests.

## Key steps

- file 

[`inst/httptest/redact.R`](https://github.com/gergness/crunchtestdemo/blob/cce311a552ee45baf4cffe5d3e99426339570bb3/inst/httptest/redact.R) 

pulls the `crunch` package's redaction file

which helps make sure that `httptest::capture_requests()` doesn't include

tokens, and also does some other pruning on the requests.

  

- file 

[`fixture-creation/fixture_1.R`](https://github.com/gergness/crunchtestdemo/blob/cce311a552ee45baf4cffe5d3e99426339570bb3/fixture-creation/fixture_1.R) 

is a replayable script that makes the requests we need for a test and saves them into

this folder 

[`tests/testthat/fixture1`](https://github.com/gergness/crunchtestdemo/tree/cce311a552ee45baf4cffe5d3e99426339570bb3/tests/testthat/fixture1).

  

- Now the test in 

[`tests/testthat/test-crunch_mean_by.R`](https://github.com/gergness/crunchtestdemo/blob/cce311a552ee45baf4cffe5d3e99426339570bb3/tests/testthat/test-crunch_mean_by.R) 

can use the fixture.

I've run the same set of tests twice, once with the options being set 

explicitly, and another with a function modeled after `with_mock_crunch()` 

from the crunch package. I modified it so that it takes a directory path,

because I would recommend not having overlapping mocks like the crunch

does.
