dream_test/matchers/equality
Equality matchers for dream_test.
These matchers compare values using Gleam’s structural equality and are
re-exported through dream_test/matchers.
Example
2 + 3
|> should
|> be_equal(5)
|> or_fail_with("2 + 3 should equal 5")
Values
pub fn be_equal(
value_or_result value_or_result: types.MatchResult(a),
expected 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
2 + 3
|> should
|> be_equal(5)
|> or_fail_with("2 + 3 should equal 5")
Parameters
value_or_result: theMatchResult(a)produced byshould(or a previous matcher)expected: the value you expect the actual value to equal
Returns
A MatchResult(a):
- On success, preserves the original value for further chaining.
- On failure, the chain becomes failed and later matchers are skipped.
pub fn not_equal(
value_or_result value_or_result: types.MatchResult(a),
unexpected unexpected: a,
) -> types.MatchResult(a)Assert that a value does not equal the unexpected value.
Uses Gleam’s structural inequality (!=).
Example
10 + 3
|> should
|> not_equal(3)
|> or_fail_with("10 + 3 should not equal 3")
Parameters
value_or_result: theMatchResult(a)produced byshould(or a previous matcher)unexpected: the value you expect the actual value to not equal
Returns
A MatchResult(a):
- On success, preserves the original value for further chaining.
- On failure, the chain becomes failed and later matchers are skipped.
