Creating a report context
This feature allows you to create a report context specifying the output directory and watermarks for coverage metrics. The context is used to generate reports.
import { createContext } from 'istanbul-lib-report';
const context = createContext({
dir: './coverage',
watermarks: {
statements: [50, 80],
functions: [50, 80],
branches: [50, 80],
lines: [50, 80]
}
});Generating a report
After creating a report context, you can generate a report in various formats (e.g., HTML, JSON) using the istanbul-reports package. This example demonstrates generating an HTML report.
import { create } from 'istanbul-reports';
const report = create('html', context);
report.execute(summarizer);nyc is a command-line-interface and library for Istanbul, a JavaScript code coverage tool. It extends Istanbul's functionality by making it easier to use directly from the command line or as part of your testing workflow. Unlike @types/istanbul-lib-report, nyc does not focus on report generation alone but provides a more comprehensive coverage solution.
Coveralls is a web service to help you track your code coverage over time, and ensure that all your new code is fully covered. While it integrates with Istanbul for generating coverage reports, its primary focus is on tracking coverage statistics across multiple projects and branches, offering a broader scope compared to @types/istanbul-lib-report.
