👁 Global Overview:

The Global course rating stands at 4.58, with recent reviews indicating that while the course covers the basics well and is great for beginners, it requires significant updates to be considered a "Masterclass" for more advanced testing scenarios in Angular. Some of the key issues mentioned include outdated code examples, deprecated functions, and a lack of coverage of more complex concepts and new features introduced in recent Angular versions, particularly Angular 17.

Pros:

• The course content is understandable and well explained, with some users highlighting the clear explanation of asynchronous testing concepts.
• It's a good starting point for beginners looking to learn Angular Unit testing and Cypress End-to-End testing.
• The course provides a solid foundation in testing Angular applications, including how to set up continuous integration servers.
• Some users found the course very detailed, especially in testing asynchronous activities and understanding micro tasks and tasks.
• It is a valuable resource for those who want to understand the basics of Jasmine testing and apply these concepts in real-world scenarios.

Cons:

• The course content is outdated in places, with some commands and practices already deprecated or replaced, such as ng build --prod being replaced by ng build --configuration production.
• Advanced concepts like marble testing are omitted, which could be beneficial for more experienced users.
• The Cypress section is covered relatively quickly, and some users encountered issues with the Cypress setup on their PCs.
• Some users lost time correcting issues that were not explicitly highlighted as outdated in the course material.
• The course lacks coverage of testing more complex scenarios such as directives and pipes, which are common components in Angular applications.
• Users reported a need for step-by-step instructions at the beginning of the course to guide beginners better.

User Experience:

• Many users found the example code provided in the course to be functional and valuable for gaining knowledge about Angular testing.
• The Q&A section was often utilized by users to find workarounds and solutions when encountering outdated content or issues with the code examples.
• Some users expressed that they had to do additional research to keep up with the evolving Angular ecosystem while following the course.

Recommendations:

• The course is recommended for beginners and those looking to refresh their knowledge of Angular testing.
• Users who are working with the latest versions of Angular should be prepared to encounter deprecated content and may need to supplement the course material with updates from the Angular documentation or community resources.
• For advanced users, it's suggested to look for more up-to-date resources or consider this course as a starting point before delving into more complex testing scenarios.

Conclusion: Overall, the course is beneficial for understanding the basics of Angular Unit and End-to-End testing but requires updates to cover recent advancements and provide guidance on advanced testing techniques. It's a solid educational resource with room for improvement in terms of content currency and coverage of complex scenarios.
