# Test.Hspec.Codewars
Utility functions for testing on Codewars with Hspec.
### Blacklisting
#### `Hidden`
```haskell
data Hidden
-- | Module to be hidden
= Module {moduleName :: String}
-- | Symbol from a module to be hidden
| FromModule {moduleName :: String, symbolName :: String}
```
#### `solutionShouldHide`
```haskell
solutionShouldHide :: Hidden -> Expectation
```
Check that solution hides a module or a symbol from a module.
```haskell
solutionShouldHide $ FromModule "Prelude" "head"
```
#### `solutionShouldHideAll`
```haskell
solutionShouldHideAll :: [Hidden] -> Expectation
```
Check that solution hides all of given modules and symbols.
```haskell
solutionShouldHideAll [FromModule "Prelude" "head", Module "Data.Set"]
```
### Approximate Equality
#### `shouldBeApprox`
```haskell
shouldBeApprox :: (Fractional a, Ord a, Show a) => a -> a -> Expectation
```
Predefined approximately equal expectation with error margin `1e-6`.
```haskell
sqrt 2.0 `shouldBeApprox` (1.4142135 :: Double)
```
#### `shouldBeApproxPrec`
```haskell
shouldBeApproxPrec :: (Fractional a, Ord a, Show a) => a -> a -> a -> Expectation
```
Create approximately equal expectation with margin.
```haskell
shouldBeApprox' = shouldBeApproxPrec 1e-9
```
