TestObject<C extends Cell> class abstract interface

TestObject is a composite of multiple TestRules that applies them sequentially to validate operations on a Cell.

Can check signals, links, elements and actions according to multiple test rules that can be combined.

Types of Rules

TestActionRule: Controls function execution.

TestSignalRule: Determines whether a Signal is processed.

TestLinkRule: Validates link establishment between Cell instances.

TestElementRule: Determines whether an element is allowed to be processed.

Example:


// Combine rules
TestObject.fromRules(rules: [rule1, rule2]);

// Or use operator +
final compositeRule = rule1 + rule2;

final test = TestObject<Cell>.fromRules(rules: [
  TestSignalRule(rule: (signal) => signal != null),
  TestLinkRule(rule: (link) => link is ValidCell)
]);

Methods

action(Function action, C cell, {Arguments? arguments}) → bool
Validates an action against test rules
any(bool test(TestRule<dynamic, Cell> element)) → bool
Checks whether any element of this iterable satisfies test.
inherited

contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
elementAt(int index) → TestRule<dynamic, Cell>
Returns the indexth element.
inherited
every(bool test(TestRule<dynamic, Cell> element)) → bool
Checks whether every element of this iterable satisfies test.

inherited
fold<T>(T initialValue, T combine(T previousValue, TestRule<dynamic, Cell> element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<TestRule<dynamic, Cell>> other) → Iterable<TestRule<dynamic, Cell>>
