Companion to the EPPlus series, specifically to Part 2: Formulas.
Covering the EPPlus syntax and implemented functions.

What would we be without some extra plugins. There are over 1000 Jasmine npm packages and we’ll cover them all here.

Make your Jasmine experience even more luscious with custom matchers and global convenience methods.
Mock global variables in your modules with jasmine.getGlobal().pi = 3.14.

Need to test async code? No problem for Jasmine. There is done() to inform Jasmine a test has finished running.

With jasmine.clock(), the value of new Date() can be manipulated.

Finally instructions on how to configure Babel for async/await in tests.

Spies, the Jasmine implementation for mocks featuring spyOn and the new spyOnProperty as well as jasmine.createSpy(Obj) and how to inspect calls made.

The basic example contains the general test suite structure and the two most used matchers toBe() (===) and toEqual() (deep compare), followed by all the other matchers that come out of the box.

To finish some helpers for your workflow: how to only have certain tests run and how to exclude tests.

Probably the most widely used JavaScript testing framework.

This tutorial covers installation, configuration and execution only. For the Jasmine syntax, see parts 2 to 4!
