isNaN (val)
Checks if the value passed as argument is NaN.
Parameters
| Object | val | The value that should be NaN. |
Throws
isNotNaN (val)
Checks if the value passed as argument is not NaN.
Parameters
| Object | val | The value that should be not NaN. |

isNotNull (val)
Checks if the value passed as argument is not null.
Parameters
| Object | val | The value that should be not null. |
Throws
isNotUndefined (val)
Checks if the value passed as argument is not undefined.
Parameters
| Object | val | The value that should be not undefined. |
Throws
isNull (val)
Checks if the value passed as argument is null.
Parameters
| Object | val | The value that should be null. |
Throws
isTrue (val)
Checks if the value passed as argument is boolean true.
Parameters
| Object | val | The value that should be boolean true. |
Throws
isUndefined (val)
Checks if the value passed as argument is undefined.
Parameters
| Object | val | The value that should be undefined. |
Throws
matches (value, expr)
Checks if the regular expression matches the string.
Parameters
| String | value | The string that should contain the regular expression pattern |
| RegExp | expr | The regular expression that should match the value |
Throws
notDeepEqual (actual, expected)
Checks if the values passed as arguments are not deep equal
Parameters
| Object | actual | The actual value |

Throws
notEqual (actual, expected)
Checks if the values passed as arguments are not equal.
Parameters
| Object | actual | The actual value |
| Object | expected | The expected value |
Throws
notStrictEqual (actual, expected)
Checks if the values passed as arguments are not strictly equal
Parameters
| Object | actual | The actual value |
| Object | expected | The expected value |
Throws
ok (value)
Checks if the value passed as argument is truthy.
Parameters
| Object | value | The value to check for truthiness |
Throws
strictEqual (actual, expected)
Checks if the values passed as arguments are strictly equal
Parameters
| Object | actual | The actual value |
| Object | expected | The expected value |
Throws
stringContains (value, pattern)
Checks if the value passed as argument contains the pattern specified.
Parameters
