Classes

CheckFailure: The result an expectation that failed for a subject..
Condition<T>: A set of expectations that are checked against the value when applied to a Subject.
ConditionSubject<T>: A Subject which records expectations and can replay them as a Condition.
Context<T>: The context for a Subject that allows asserting expectations and creating nested subjects.
Extracted<T>: A property extracted from a value being checked, or a rejection.
FailureDetail: The context for a failed expectation.
Rejection: A description of a value that failed an expectation.
Subject<T>: A target for checking expectations against a value in a test.

describe<T>(Condition<T> condition) → Iterable<String>: Creates a description of the expectations checked by condition.
describeAsync<T>(Condition<T> condition) → Future<Iterable<String>>: Creates a description of the expectations checked by condition.
escape(String output) → String: Returns output with all whitespace characters represented as their escape sequences.
indent(Iterable<String> lines, [int depth = 1]) → Iterable<String>
literal(Object? object) → Iterable<String>: Returns a pretty-printed representation of object.
postfixLast(String postfix, Iterable<String> lines) → Iterable<String>: Append postfix to the last line of lines.
prefixFirst(String prefix, Iterable<String> lines) → Iterable<String>: Prepends prefix to the first line of lines.
softCheck<T>(T value, Condition<T> condition) → CheckFailure?: Checks whether value satisfies all expectations invoked in condition, without throwing an exception.
softCheckAsync<T>(T value, Condition<T> condition) → Future<CheckFailure?>: Checks whether value satisfies all expectations invoked in condition, without throwing an exception.
