R: Expectation class.

expectation {testthat} | R Documentation

## Expectation class.

### Description

You generate an expectation object with `expectation`, and signal an expectation with `expect`. If you're making your own expectation function, you'll typically call `expect(condition, "failure message")`. See the source code for the built-in expectations for details.

### Usage

    expectation(type, message, srcref = NULL)

    expect(exp, ..., srcref = NULL)

    is.expectation(x)

### Arguments

`message` | A text description of failure
`srcref` | Source reference, if known
`x` | object to test for class membership
`passed` | a single logical value indicating whether the test passed (`TRUE`), failed (`FALSE`), or threw an error (`NA`)
