## assert/check/test/Crisp

### Description

Validation checks to test if a given object is crisp.

### Usage

    testCrisp(object, errormsg = "This is not crisp.")

    checkCrisp(object, errormsg = "This is not crisp.")

    assertCrisp(object, errormsg = "This is not crisp.")

### Arguments

`object` | object to test
`errormsg` | error message to overwrite default if check fails

### Value

If check passes then `assert` returns `object` invisibly and `test`/`check` return `TRUE`. If check fails, `assert` stops code with error, `check` returns an error message as string, and `test` returns `FALSE`.

### Examples

    testCrisp(Set$new(1))
    testCrisp(FuzzySet$new(1, 0.5))
