How do I check my test coverage?
How to Calculate Test Coverage. Calculating test coverage is actually fairly easy. You can simply take the number of lines that are covered by a test (any kind of test, across your whole testing strategy) and divide by the total number of lines in your application.
What is karma in Angular testing?
Karma is a direct product of the AngularJS team from struggling to test their own framework features with existing tools. As a result of this, they made Karma and have transitioned it to Angular as the default test runner for applications created with the Angular CLI.

What is karma coverage Istanbul reporter?
What is karma-coverage-istanbul-reporter? A karma reporter that uses the latest istanbul 1. x APIs (with full sourcemap support) to report coverage.
How does code coverage work?
Code coverage is performed to verify the extent to which the code has been executed. Code coverage tools use static instrumentation in which statements monitoring code execution are inserted at necessary junctures in the code. Now, adding instrumentation code does result in increased execution time and code length.
What are angular test coverage branches?
Branch coverage is a testing method, which aims to ensure that each one of the possible branch from each decision point is executed at least once and thereby ensuring that all reachable code is executed. That is, every branch taken each way, true and false.
What is coverage testing?
Coverage-based testing aims to demonstrate a specific type of coverage of one or another aspect of an IT-system. This can be done by designing test situations and test cases with test design techniques.
What is a good test coverage?
With that being said it is generally accepted that 80% coverage is a good goal to aim for. Trying to reach a higher coverage might turn out to be costly, while not necessary producing enough benefit. The first time you run your coverage tool you might find that you have a fairly low percentage of coverage.
What is karma and Protractor?
What’s the difference between Karma and Protractor? When do I use which? Karma is a great tool for unit testing, and Protractor is intended for end-to-end or integration testing. This means that small tests for the logic of your individual controllers, directives, and services should be run using Karma.
What is Karma and Jasmine?

A karma theory considers not only the action, but also actor’s intentions, attitude, and desires before and during the action. The karma concept thus encourages each person to seek and live a moral life, as well as avoid an immoral life.
How is code coverage calculated?
To calculate the code coverage percentage, simply use the following formula: Code Coverage Percentage = (Number of lines of code executed by a testing algorithm/Total number of lines of code in a system component) * 100.
What is path coverage in testing?
Path coverage testing is a specific kind of methodical, sequential testing in which each individual line of code is assessed. As a type of software testing, path coverage testing is in the category of technical test methods, rather than being part of an overarching strategy or “philosophy” of code.
