Angular Testing with Karma
Content length: approx.
The value of automated testing is widely known; but executing on it can be difficult, tedious, and time-consuming. Many developers and organizations know there is benefit to be had but haven't fully rolled out automated testing.
In this class, we go in-depth on the machinery, techniques, and trade-offs of how and where to test Angular applications using Karma. Karma has been the default testing choice for Angular applications, and therefore is in very wide use.
We weave broader testing topics through the technical machinery, and show how some of the same tools (especially Jasmine) can be used for testing other parts of your stack, Node applications.
Oasis Digital developers have particular experience using these tools to produce the right tests, at the right time, quickly enough to produce value before other urgencies derail a testing effort. We work with your team in class and if needed afterward, to bring this value to your organization.
(This class is primarily about unit and functional/integration testing with Karma, Jasmine, and Angular and to a lesser extent Node code. We also offer other classes featuring other frameworks and other types of testing.)

Training FAQs
- Q: Is this taught in person?
- A: We offer training both in-person and online via remote conferencing.
- Q: How does the remote option work?
- A: Much like an in-person class, it's conducted by our expert instructors in real time. The instructors answer questions, assist students, etc. We strive to offer as much of the in-person experience as possible, online.
- Q: Can the content be customized?
- A: For private team classes, we *always discuss your goals, the class contents, any specials areas for extra coverage, etc. in advance. We customize both the contents and length (number of days) to your needs.
- Q: Can we schedule a private class any time?
- A: Our classes are taught by developers who use the subject technologies in their daily work, so we carefully assign the right developer/trainer to your class, for a good experience and knowledge match. Please contact us to arrange a date.
