Difference between .toBe() and .toEqual() - Jasmine Karma testcases [duplicate]

Question

I am using Jasmine karma test case for a while and found tests failing sometime because of using .toBe() instead of .toEqual(). What is the difference between .toBe() and .toEqual() and when you use these?

Answer 1

• toBe() comparison is strict (ex.: obj1 === obj2 )
  if comparing two objects the identity of the objects is taken in consideration.

• while toEqual() takes only value of the entries in consideration ( it compares object like underscore's isEqual method ).

Answer 2

here is an example that explains the difference between both of them

describe("Included matchers:", function() {
it("The 'toBe' matcher compares with ===", function() {
var a = 12;
var b = a;

expect(a).toBe(b);
expect(a).not.toBe(null);
});

describe("The 'toEqual' matcher", function() {

it("works for simple literals and variables", function() {
  var a = 12;
  expect(a).toEqual(12);
});

it("should work for objects", function() {
  var foo = {
    a: 12,
    b: 34
  };
  var bar = {
    a: 12,
    b: 34
  };
  expect(foo).toEqual(bar);
});
});
});

you can find more details about other Matchers in the official website
