Is there a way to exclude all files with 100% or at a threshold across the board from karma-coverage text reporter results? - unit-testing

Question

This is very picky of me, I know, but I have a large Angular application where many files are covered at 100% or pretty darn close to it, and I want to exclude those results, so I can just deal with the ones I need to and don't have all the extra noise.
I don't want to exclude files by name because if they change they may go below the OK threshold.
My karma.conf.js (I'm aware I may not need some of the plugins, this is a shared file by the team):
// Karma configuration file, see link for more information
// https://karma-runner.github.io/1.0/config/configuration-file.html
module.exports = function (config) {
config.set({
basePath: '',
frameworks: ['jasmine', '#angular-devkit/build-angular'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-jasmine-html-reporter'),
require('karma-coverage'),
require('#angular-devkit/build-angular/plugins/karma')
],
reporters: ['progress', 'coverage'],
coverageReporter: {
reporters: [
{type: 'text'},
{type: 'text-summary'},
]
},
browsers: ['ChromeHeadless'],
preprocessors: {'**/*.ts': ['coverage']},
restartOnFileChange: true,
});
};
and I'm gonna try to attach a screenshot here of my sample output in the type: 'text' coverageReporter:
I've tried searching SO and karma / karma-coverage documentation, but I only can find excluding files/paths specifically by name, or updating thresholds, but the latter seems to be only for determining what colors show up. Thank you~
EDIT: And since I only have one file per directory, would also be useful to not duplicate the numbers by printing them for the directory AND the one file under it. Thinking I may just have to dig into the weeds and create a pull request or something.

For this you can generate coverage reports in HTML format. There you will get option to sort files based on code-coverage.
To enable such reports you will have to do update coverageReporter property in your karma configurations -
coverageReporter: {
includeAllSources: true,
dir: 'coverage/',
reporters: [
{type: 'text'},
{type: 'text-summary'},
{type: 'html', subdir: 'html/'}
]
},
Reports will be generated within coverage/html folder.
