# power_assert.cr
[](http://www.docrystal.org/github.com/rosylilly/power_assert.cr)
PowerAssert provides the more powerful assertion to you.
## Usage
Very simple.
```crystal
# spec/my_lib_spec.cr
describe MyLib do
describe ".major_version" do
it "should be equal 1" do
assert MyLib.major_version == 1
end
end
end
```
If `MyLib.major_version` is 2:
```
F
Failures:
1) MyLib .major_version should be equal 1
Failure/Error: assert MyLib.major_version == 1
MyLib.major_version == 1
| | |
| | 1
| false
2
# ./spec/my_lib_spec.cr:6
```
more examples in `spec`.
:tada: Happy testing! :tada:
## Configure
- `global_indent : Int` : A indent size of assertion messages.
- `sort_by : Symbol` : Sort order of breakdowns. allowed: `:default`, `:reverse`, `:left` and `:right`.
- `expand_block : Bool` : Show block's codes in the breakdown.
## Example Outputs
Run `crystal spec`.
```
