karma-summary-reporter

karma-summary-reporter

Show a table detailing the test results for all connected browsers at the end of a test run. This gives a better overview which browsers are broken than the output of other reporters.

The plugin is intended to be used in addition to some other reporter that shows you the error details. This plugin only shows an overview of passed and failed testcases, no more detailed information:

Use cases

Testing in several browsers

When you test in several browsers, the sequential test output of all the browsers can be unwieldy to quickly grasp the problems in the tests. The summary table provided by this reporter shows the failing tests in a compact format that is easy to grasp at a glance:

Here we can clearly see that addPrefix() has some general problem while the error in stripPrefix() seems to be specific to IE.

Feature tests

The summary table is also useful if you want to (ab-)use karma to run feature tests, like checking which standard string functions are available:

We can see that IE is lacking some features here.

Config

module.exports = function(config) {
   config.set({
      reporters: ['progress', 'summary'],
      summaryReporter: {
         // 'failed', 'skipped' or 'all'
         show: 'failed',
         // Limit the spec label to this length
         specLength: 50,
         overviewColumn: true
      }
   });
};

show

Select which tests are dislayed in the summary. There are three choices:

• 'failed': Only show tests that failed in some browser (default)
• 'skipped': Additionally show tests that got skipped in some browser
• 'all': Show all test, also ones that didn't fail

specLength

Space reserved to display the spec label (width of the first column in the results table).

overviewColumn

Shows a overview column in the results table, showing the total result of a test over all browsers ("failed" if the test failed anywhere, ...). In the above examples this is the column with the "all" header. Setting this option to false disables this column.
