TS-mockito: Mocking Library for TypeScript


Mocking library for TypeScript inspired by

1.x to 2.x migration guide

1.x to 2.x migration guide

Main features

  • Strongly typed
  • IDE autocomplete
  • Mock creation (mock) (also abstract classes) #example
  • Spying on real objects (spy) #example
  • Changing mock behavior (when) via:
  • Checking if methods were called with given arguments (verify)
    • anything, notNull, anyString, anyOfClass etc. - for more flexible comparision
    • once, twice, times, atLeast etc. - allows call count verification #example
    • calledBefore, calledAfter - allows call order verification #example
  • Resetting mock (reset, resetCalls) #example, #example
  • Capturing arguments passed to method (capture) #example
  • Recording multiple behaviors #example
  • Readable error messages (ex. 'Expected "convertNumberToString(strictEqual(3))" to be called 2 time(s). But has been called 1 time(s).')


npm install ts-mockito --save-dev



// Creating mock
let mockedFoo:Foo = mock(Foo);

// Getting instance from mock
let foo:Foo = instance(mockedFoo);

// Using instance in source code

// Explicit, readable verification

Stubbing method calls

// Creating mock
let mockedFoo:Foo = mock(Foo);

// stub method before execution

// Getting instance
let foo:Foo = instance(mockedFoo);

// prints three

// prints null, because "getBar(999)" was not stubbed

Stubbing getter value

// Creating mock
let mockedFoo:Foo = mock(Foo);

// stub getter before execution

// Getting instance
let foo:Foo = instance(mockedFoo);

// prints three

Stubbing property values that have no getters

Syntax is the same as with getter values.

Please note, that stubbing properties that don't have getters only works if Proxy object is available (ES6).

Call count verification

// Creating mock
let mockedFoo:Foo = mock(Foo);

// Getting instance
let foo:Foo = instance(mockedFoo);

// Some calls

// Call count verification
verify(mockedFoo.getBar(1)).once();               // was called with arg === 1 only once
verify(mockedFoo.getBar(2)).twice();              // was called with arg === 2 exactly two times
verify(mockedFoo.getBar(between(2, 3))).thrice(); // was called with arg between 2-3 exactly three times
verify(mockedFoo.getBar(anyNumber()).times(4);    // was called with any number arg exactly four times
verify(mockedFoo.getBar(2)).atLeast(2);           // was called with arg === 2 min two times
verify(mockedFoo.getBar(anything())).atMost(4);   // was called with any argument max four times
verify(mockedFoo.getBar(4)).never();              // was never called with arg === 4

Call order verification

// Creating mock
let mockedFoo:Foo = mock(Foo);
let mockedBar:Bar = mock(Bar);

// Getting instance
let foo:Foo = instance(mockedFoo);
let bar:Bar = instance(mockedBar);

// Some calls

// Call order verification
verify(mockedFoo.getBar(1)).calledBefore(mockedBar.getFoo(2));    // foo.getBar(1) has been called before bar.getFoo(2)
verify(mockedBar.getFoo(2)).calledAfter(mockedFoo.getBar(1));    // bar.getFoo(2) has been called before foo.getBar(1)
verify(mockedFoo.getBar(1)).calledBefore(mockedBar.getFoo(999999));    // throws error (mockedBar.getFoo(999999) has never been called)

Throwing errors

let mockedFoo:Foo = mock(Foo);

when(mockedFoo.getBar(10)).thenThrow(new Error('fatal error'));

let foo:Foo = instance(mockedFoo);
try {
} catch (error:Error) {
    console.log(error.message); // 'fatal error'

Custom function

You can also stub method with your own implementation

let mockedFoo:Foo = mock(Foo);
let foo:Foo = instance(mockedFoo);

when(mockedFoo.sumTwoNumbers(anyNumber(), anyNumber())).thenCall((arg1:number, arg2:number) => {
    return arg1 * arg2; 

// prints '50' because we've changed sum method implementation to multiply!
console.log(foo.sumTwoNumbers(5, 10));

Resolving / rejecting promises

You can also stub method to resolve / reject promise

let mockedFoo:Foo = mock(Foo);

when(mockedFoo.fetchData("a")).thenResolve({id: "a", value: "Hello world"});
when(mockedFoo.fetchData("b")).thenReject(new Error("b does not exist"));

Resetting mock calls

You can reset just mock call counter

// Creating mock
let mockedFoo:Foo = mock(Foo);

// Getting instance
let foo:Foo = instance(mockedFoo);

// Some calls
verify(mockedFoo.getBar(1)).twice();      // getBar with arg "1" has been called twice

// Reset mock

// Call count verification
verify(mockedFoo.getBar(1)).never();      // has never been called after reset

You can also reset calls of multiple mocks at once resetCalls(firstMock, secondMock, thirdMock)

Resetting mock

Or reset mock call counter with all stubs

// Creating mock
let mockedFoo:Foo = mock(Foo);

// Getting instance
let foo:Foo = instance(mockedFoo);

// Some calls
console.log(foo.getBar(1));               // "one" - as defined in stub
console.log(foo.getBar(1));               // "one" - as defined in stub
verify(mockedFoo.getBar(1)).twice();      // getBar with arg "1" has been called twice

// Reset mock

// Call count verification
verify(mockedFoo.getBar(1)).never();      // has never been called after reset
console.log(foo.getBar(1));               // null - previously added stub has been removed

You can also reset multiple mocks at once reset(firstMock, secondMock, thirdMock)

Capturing method arguments

let mockedFoo:Foo = mock(Foo);
let foo:Foo = instance(mockedFoo);

// Call method
foo.sumTwoNumbers(1, 2);

// Check first arg captor values
const [firstArg, secondArg] = capture(mockedFoo.sumTwoNumbers).last();
console.log(firstArg);    // prints 1
console.log(secondArg);    // prints 2

You can also get other calls using first(), second(), byCallIndex(3) and more...

Recording multiple behaviors

You can set multiple returning values for same matching values

const mockedFoo:Foo = mock(Foo);


const foo:Foo = instance(mockedFoo);

console.log(foo.getBar(1));    // one
console.log(foo.getBar(1));    // two
console.log(foo.getBar(1));    // three
console.log(foo.getBar(1));    // three - last defined behavior will be repeated infinitely

Another example with specific values

let mockedFoo:Foo = mock(Foo);

when(mockedFoo.getBar(1)).thenReturn('one').thenReturn('another one');

let foo:Foo = instance(mockedFoo);

console.log(foo.getBar(1));    // one
console.log(foo.getBar(2));    // two
console.log(foo.getBar(1));    // another one
console.log(foo.getBar(1));    // another one - this is last defined behavior for arg '1' so it will be repeated
console.log(foo.getBar(2));    // two
console.log(foo.getBar(2));    // two - this is last defined behavior for arg '2' so it will be repeated

Short notation:

const mockedFoo:Foo = mock(Foo);

// You can specify return values as multiple thenReturn args
when(mockedFoo.getBar(anyNumber())).thenReturn('one', 'two', 'three');

const foo:Foo = instance(mockedFoo);

console.log(foo.getBar(1));    // one
console.log(foo.getBar(1));    // two
console.log(foo.getBar(1));    // three
console.log(foo.getBar(1));    // three - last defined behavior will be repeated infinity

Possible errors:

const mockedFoo:Foo = mock(Foo);

// When multiple matchers, matches same result:

const foo:Foo = instance(mockedFoo);
foo.getBar(3); // MultipleMatchersMatchSameStubError will be thrown, two matchers match same method call

Mocking interfaces

You can mock interfaces too, just instead of passing type to mock function, set mock function generic type Mocking interfaces requires Proxy implementation

let mockedFoo:Foo = mock<FooInterface>(); // instead of mock(FooInterface)
const foo: SampleGeneric<FooInterface> = instance(mockedFoo);

Mocking types

You can mock abstract classes

const mockedFoo: SampleAbstractClass = mock(SampleAbstractClass);
const foo: SampleAbstractClass = instance(mockedFoo);

You can also mock generic classes, but note that generic type is just needed by mock type definition

const mockedFoo: SampleGeneric<SampleInterface> = mock(SampleGeneric);
const foo: SampleGeneric<SampleInterface> = instance(mockedFoo);

Spying on real objects

You can partially mock an existing instance:

const foo: Foo = new Foo();
const spiedFoo = spy(foo);


console.log(foo.getBar(3)); // 'one'
console.log(foo.getBaz()); // call to a real method

You can spy on plain objects too:

const foo = { bar: () => 42 };
const spiedFoo = spy(foo);;

console.log(capture(; // [42]

HTML Tutorial For Beginners

The prospect of learning HTML can seem confusing at first: where to begin, what to learn, the best ways to learn — it can be difficult to get started. In this article, we’ll explore the best ways for learning HTML to assist you on your programming journey.

What is HTML?

Hypertext Markup Language (HTML) is the standard markup language for documents meant to be displayed in a web browser. Along with Cascading Style Sheets (CSS) and JavaScript, HTML completes the trio of essential tools used in creating modern web documents.

HTML provides the structure of a webpage, from the header and footer sections to paragraphs of text, videos, and images. CSS allows you to set the visual properties of different HTML elements, like changing colors, setting the order of blocks on the screen, and defining which elements to display. JavaScript automates changes to HTML and CSS, for example, making the font larger in a paragraph when a user clicks a button on the page.

Commonly Used HTML Tags with Examples

HTML tags are keywords used in HTML to display web-pages with certain properties. They are further used for defining HTML elements. An HTML element consists of a starting tag, some content, and an ending tag. The web browser reads the HTML document from top to bottom, left to right. Each HTML tag defines a new property that helps in rendering the website.



The ‘<>’ brackets contain an HTML tag. There are two types of HTML tags- empty tags or singleton tags and container tags. Singleton tags or empty tags do not contain any content such as an image or a paragraph and hence do not need to be closed, whereas container tags should be closed.


  1. Some Content

Examples of:

Empty tag: 


Container tags: 



  1. <!DOCTYPE>
  2. Paragraph

  3. Heading

  4. Bold
  5. Italic
  6. Underline


HTML Tags example

Head tags:

,<style>,<script>,<link>,<meta> and <base>. <p>Text-formatting tags:</p> <p><h>,<b>,<strong>,<small>,<pre>,<i>,<em>,<sub>,<sup>,<ins>,<dfn>,<del>,<div> and <span>.</p> <p>Link tags:</p> <p><a>, <base>.</p> <p>List tags:</p> <ul>, <ol>, <li>, <dl>, <dd> <p>Table tags:</p> <table> ,<tr> , <td>, <th>, <thead>, <tbody>, <tfoot>. <p>Form tags:</p> <form>, <input>, <select>, <option>, <button>, <label>, <fieldset>, <textarea>. <p>Scripting tags:</p> <script>, <noscript> Image and Object tags: <img>, <figure>, <figcaption>, <area>, <map>, <object>. Here is an alphabetical list of tags used in HTML.

Know Everything About HTML With HTML Experts

HTML stands for a hypertext markup language. For the designs to be displayed in web browser HTML is the markup language. Technologies like Cascading style sheets (CSS) and scripting languages such as JavaScript assist HTML. With the help of HTML websites and the web, designs are created. Html has a wide range of academic applications. HTML has a series of elements. HTML helps to display web content. Its elements tell the web how to display the contents.

The document component of HTML is known as an HTML element. HTML element helps in displaying the web pages. An HTML document is a mixture of text nodes and HTML elements.

Basics of HTML are-

The simple fundamental components oh HTML is

  1. Head- the setup information for the program and web pages is carried in the head
  2. Body- the actual substance that is to be shown on the web page is carried in the body
  3. HTML- information starts and ends with and labels.
  4. Comments- come up in between
