Is Chai’s assert.equal() equivalent of Node’s assert module’s assert.strictEqual()?

how to run test in the terminal?


oh i just found out : npm test

No, assert.equal( ) uses ‘==’ for comparison whereas assert.strictEqual( ) uses ‘===’ for comparison.
For more info check : https://nodejs.org/api/assert.html

I think masakudamatsu was referring to Chai’s ‘assert.equal()’ method as mentioned in the exercise’s instructions. Fortunately for us Chai’s ‘assert.equal()’ method also asserts non-strict equality (==), much like Node’s ‘assert.equal()’.


Chai’s assert option also has methods for ‘strict’ and ‘deep’ equality. There doesn’t seem one for ‘strictDeep’ equality though.

thank you
i have the same doubt to how to run in the terminal

Hello please, what do I type in the bash terminal to run the test?
I have wasted so much time just trying to find out how to run the test.

Typing ‘npm test’ as @objectwhiz71086 said he found out above, did not work.

Can anyone help please?

Thanks in advance.
