# clarunit | ||
|
||
This package allows you to write unit tests for Clarity smart contracts in the | ||
Clarity language itself, as opposed to TypeScript. `clarunit` will automatically | ||
detect test files and test functions. | ||
|
||
An example Clarinet-sdk project using `clarunit` can be found in the `example` | ||
folder. | ||
|
||
## Setup | ||
|
||
1. Install package `@stacks/clarunit` using your favourite package manager. (Be sure to | ||
pin the version!) | ||
2. Create a test file in your existing `tests` folder, you can use any name but | ||
using `clarunit.test.ts` is recommended. | ||
3. Add the following to the newly created file: | ||
```ts | ||
import { clarunit } from "clarunit"; | ||
clarunit(simnet); | ||
``` | ||
4. Run your tests per usual using `npm test` or `yarn test`. | ||
|
||
`clarunit` takes configuration from Clarinet via `Clarinet.toml`. It | ||
automatically detects all instantiated test contracts. | ||
|
||
## Unit testing | ||
|
||
### Adding tests | ||
|
||
To write unit tests, follow these steps: | ||
|
||
1. Create a new Clarity contract in the `./tests` folder. It can have any name | ||
but it should end in `_test.clar`. Files that do not follow this convention | ||
are ignored. (For example: `my-contract_test.clar` will be included and | ||
`my-contract.clar` will not.) | ||
2. Add the new Clarity contract to `Clarinet.toml`. | ||
3. Write unit tests as public functions, the function name must start with | ||
`test-`. | ||
|
||
### Writing tests | ||
|
||
Unit test functions should be public without parameters. If they return an `ok` | ||
response of any kind, the test is considered to have passed whereas an `err` | ||
indicates a failure. The failure value is printed so it can be used to provide a | ||
helpful message. The body of the unit test is written like one would usually | ||
write Clarity, using `try!` and `unwrap!` and so on as needed. | ||
|
||
Example: | ||
|
||
```clarity | ||
(define-public (test-my-feature) | ||
(begin | ||
(unwrap! (contract-call? .some-project-contract my-feature) (err "Calling my-feature failed")) | ||
(ok true) | ||
) | ||
) | ||
``` | ||
|
||
### Prepare function | ||
|
||
Sometimes you need to run some preparation logic that is common to all or | ||
multiple unit tests. If the script detects a function called `prepare`, it will | ||
be invoked before calling the unit test function itself. The `prepare` function | ||
should return an `ok`, otherwise the test fails. | ||
|
||
```clarity | ||
(define-public (prepare) | ||
(begin | ||
(unwrap! (contract-call? .some-project-contract prepare-something) (err "Preparation failed")) | ||
(ok true) | ||
) | ||
) | ||
(define-public (test-something) | ||
;; prepare will be executed before running the test. | ||
) | ||
``` | ||
|
||
### Annotations | ||
|
||
You can add certain comment annotations before unit test functions to add | ||
information or modify behaviour. Annotations are optional. | ||
|
||
| Annotation | Description | | ||
|-----------------------|----------------------------------------------------------------------------------------------------------------------------------------------| | ||
| `@name` | Give the unit test a name, this text shows up when running unit tests. | | ||
| `@no-prepare` | Do not call the `prepare` function before running this unit test. | | ||
| `@prepare` | Override the default `prepare` function with another. The function name should follow the tag. | | ||
| `@caller` | Override the default caller when running this unit test. Either specify an account name or standard principal prefixed by a single tick `'`. | | ||
| `@mine-blocks-before` | Mine a number of blocks before running the test. The number of blocks should follow the tag. | | ||
|
||
Examples: | ||
|
||
```clarity | ||
(define-public (prepare) (ok "Default prepare function")) | ||
(define-public (custom-prepare) (ok "A custom prepare function")) | ||
;; A test without any annotations | ||
(define-public (test-zero) (ok true)) | ||
;; @name A normal test with a name, the prepare function will run before. | ||
(define-public (test-one) (ok true)) | ||
;; @name This test will be executed without running the default prepare function. | ||
;; @no-prepare | ||
(define-public (test-two) (ok true)) | ||
;; @name Override the default prepare function, it will run custom-prepare instead. | ||
;; @prepare custom-prepare | ||
(define-public (test-three) (ok true)) | ||
;; @name This test will be called with tx-sender set to wallet_1 (from the settings toml file). | ||
;; @caller wallet_1 | ||
(define-public (test-four) (ok true)) | ||
;; @name This test will be called with tx-sender set to the specified principal. | ||
;; @caller 'ST2CY5V39NHDPWSXMW9QDT3HC3GD6Q6XX4CFRK9AG | ||
(define-public (test-five) (ok true)) | ||
;; @name Five blocks are mined before this test is executed. | ||
;; @mine-blocks-before 5 | ||
(define-public (test-six) (ok true)) | ||
``` | ||
|
||
