## assert/check/test/Contains

### Description

Validation checks to test if given elements are contained in a set.

### Usage

    testContains(
      object,
      elements,
      errormsg = "elements are not contained in the set"
    )

    checkContains(
      object,
      elements,
      errormsg = "elements are not contained in the set"
    )

    assertContains(
      object,
      elements,
      errormsg = "elements are not contained in the set"
    )

### Arguments

`object` | object to test
`elements` | elements to check
`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

    testContains(Set$new(1,2,3), c(1,2))
    testContains(Set$new(1,2,3), c(3,4))
