equality

Equality matchers for dream_test.

These matchers compare values using Gleam’s structural equality. They’re re-exported through dream_test/assertions/should.

Usage

import dream_test/assertions/should.{should, equal, not_equal, or_fail_with}

// Check equality
result
|> should()
|> equal(42)
|> or_fail_with("Should be 42")

// Check inequality
result
|> should()
|> not_equal(0)
|> or_fail_with("Should not be zero")

Values

equal

</>

pub fn equal(
  value_or_result: types.MatchResult(a),
  expected: a,
) -> types.MatchResult(a)

Assert that a value equals the expected value.

Uses Gleam’s structural equality (==). Works with any type that supports equality comparison.

Example

add(2, 3)
|> should()
|> equal(5)
|> or_fail_with("2 + 3 should equal 5")

not_equal

</>

pub fn not_equal(
  value_or_result: types.MatchResult(a),
  unexpected: a,
) -> types.MatchResult(a)

Assert that a value does not equal the unexpected value.

Uses Gleam’s structural inequality (!=).

Example

divide(10, 3)
|> should()
|> not_equal(3)
|> or_fail_with("10/3 should not equal 3 exactly")
