# Should
lightweight test environment
## Install
```
go get github.com/maprost/should
```
## Supported methods
- `should.BeEqual`(`t`, `element`, `element`) -> check if two elements are equal
- `should.NotBeEqual`(`t`,`element`, `element`) -> check if two elements are not equal
- `should.BeNil`(`t`,`element`) -> check if an element it nil
- `should.NotBeNil`t`,`(`element`) -> check if an element is not nil
- `should.BeTrue`(`t`,`element`) -> check if an element is `true`
- `should.BeFalse`(`t`,`element`) -> check if an element is `false`
- `should.HaveLength`(`t`,`collection`, `length`) -> (only for `array`/`slice`/`map`) check the length of the collection
- `should.Contain`(`t`,`collection`, `element`) -> (only for `array`/`slice`/`map`/`string`) check if the collection contains the element
- `should.NotContain`(`t`,`collection`, `element`) -> (only for `array`/`slice`/`map`) check if the collection contains not the element
- `should.BeSimilar`(`t`,`collection`, `collection`) -> (only for `array`/`slice`) check if the two collections contains the same elements
- `should.NotBeSimilar`(`t`,`collection`, `collection`) -> (only for `array`/`slice`) check if the two collections contains at least one different element
- `should.Fail` -> stops the tests with the given error message
## Usage
Please look into the test files to see the possibilities. For the first look
here some examples:
```go
func TestSimple(t *testing.T) {
should.BeEqual(t, 1, 1, "should be equal")
should.BeNil(t, nil)
should.NotBeNil(t, 1)
should.BeTrue(t, true)
should.BeFalse(t, false)
should.NotBeEqual(t, 1, 2)
should.NotBeEqual(t, 1.0, 1)
should.NotBeEqual(t, int64(1), int32(1))
}
func TestDataStructures(t *testing.T) {
should.HaveLength(t, []int{1, 2, 3}, 3)
should.HaveLength(t, [3]int{1, 2, 3}, 3)

## Output
The output of a failed test shows you the actual and expected value and a stacktrace.
```
