    Finally, we pull the keys of the questions attribute to get the controls that are part of the FormGroup. Hot Network Questions. Trying to spy on the private method in the usual way caused issues. If the user cares more about how a property is determined, then it should probably be a method with a verb phrase name. That is useful when you want to isolate calls to non-public members and types, such as:.

    Writing unit test for private methods and public methods is similar. But since you are unit testing an instance of an Angular component.If you were to run your unit tests at this point, you might come across some serious issues.

    Instability: private methods are more likely to change, and when they do, so will the tests. This costs time. Exposure: testing private methods.So you can return values, or callThrough when creating the spy.

    Which means you can't write your unit test in TypeScript and access the private variables. Or can you? TypeScript is just JavaScript with Sugar.There is a restriction on private static fields: Only the class which defines the private static field can access the field.

    An attribute directive modifies the behavior of an element, component or another directive. Its name reflects the way the directive is applied: as an attribute.What separates all these verb phrases from method names is that they are not imperative.

    Just as type annotations on APIs help users of your code, types on private members help maintainers. DON'T redundantly type annotate initialized local variables.By default, all constructors are publicwhich effectively amounts to them being visible everywhere the class is visible this means that a constructor of an internal class is only visible within the same module.

    The effects on subject variable types accurately reflect JavaScript semantics (e.g. double-equals let y = x || { name: "test" }; // y is of type Entity.Angular 2 templates use the double-curly syntax for outputting variables, just like Angular 1.
