# Test Driven Development in C
|
||||
|
||||
|
||||
---
|
||||
### TDD recap
|
||||
![[TDD cycle.excalidraw]]
|
||||
* good for unit tests, if requirements are known (specification exists)
|
||||
|
||||
---
|
||||
### cgreen testing framework
|
||||
* readable
|
||||
* mocking support
|
||||
* different test reporters
|
||||
* align nicely in CI (`cobertura`/`xJunit`)
|
||||
* user friendly (`pretty`)
|
||||
* test discovery (`cgreen-runner`)
|
||||
|
||||
---
|
||||
### Example: "Calculator"
|
||||
`inc/my_fancy_calculator.h`:
|
||||
```c
|
||||
int add(int a, int b);
|
||||
```
|
||||
|
||||
`src/my_fancy_calculator.c`:
|
||||
```c
|
||||
#include "my_fancy_calculator.h"
|
||||
|
||||
int add(int a, int b) {
|
||||
return a - b;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
### Unit tests with cgreen
|
||||
`test/my_fancy_test.c`:
|
||||
```c
|
||||
#include <cgreen/cgreen.h>
|
||||
#include <my_fancy_calculator.h>
|
||||
|
||||
Ensure(my_fancy_calculator_can_do_addition) {
|
||||
assert_that(add(2, 3), is_equal_to(5));
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
* automatic test discovery
|
||||
`cgreen_runner libdemo_test.so`:
|
||||
```
|
||||
Running "libdemo_test" (1 test)...
|
||||
../test/my_fancy_test.c:5: Failure: default -> my_fancy_calculator_can_do_addition
|
||||
Expected [add(2, 3)] to [equal] [5]
|
||||
actual value: [-1]
|
||||
expected value: [5]
|
||||
|
||||
"default": 1 failure in 30ms.
|
||||
Completed "libdemo_test": 1 failure in 30ms.
|
||||
```
|
||||
|
||||
---
|
||||
### BDD
|
||||
Behavioral Driven Development
|
||||
|
||||
* isolated tests
|
||||
* via mocking
|
||||
* SDKs
|
||||
* Network
|
||||
* etc
|
||||
* via test fixtures (`BeforeEach`/`AfterEach`)
|
||||
* context setup and tear down
|
||||
* good for reproducing bugs
|
||||
|
||||

|
||||

### Whats next?
|
||||
Try it out!
|
||||
|
||||
* [cgreen tutorial](https://cgreen-devs.github.io/cgreen/cgreen-guide-en.html)
|
||||
* [cgreen repo](https://github.com/cgreen-devs/cgreen)
|
||||
* [cgreen cheat sheet](https://cgreen-devs.github.io/cgreen/cheat-sheet.html)
|
||||
|
||||
---
|
||||
### Some disclaimers
|
||||
* cgreen's buildsystem is `CMAKE`
|
||||
* `meson` usage with `cgreen-runner` does not work out of the box
|
||||
* see [repo of this talk](https://git.dezentrale.cloud/oniboni/tdd-in-c.git) for example setup
|
||||
* but.. cgreen is availabe on most common linux distros (`-lcgreen`, `find_program`, etc should work just fine)
|
||||
|
||||
---
|
||||
### [backup] TDD test structure
|
||||
|
||||
* arrange
|
||||
* act -- test function
|
||||
* assert
|
||||
|
||||
---
|
||||
### [backup] BDD test structure
|
||||
|
||||
* arrange (via test fixtures)
|
||||
* expect -- setup behavior of mocks
|
||||
* act -- entry function to trigger behavior
|
||||
* (assert) -- check post conditions
