+
+A Karma plugin. Adds untested files to coverage statistic
+
+## Why?
+
+If your project has singe entracne point for your test files (e.g. `test.(ts|js)` file which gathers all `*.spec.(ts|js))`) - you probably facing an issue, that if files with source code aren't imported directly in one of `*.spec.(ts|js))` files - such a file doesn't shows up in coverate report at all, which creates higher coverate result then they are in reality.
+
+This karma plugin tries to fix this issue by going through all source files and including them explicitly to coverage result.
+
+Plugin works with both: TypeScript (`*.ts`) and JavaScript (`*.js`) files
+
+## Usage
+
+`karma.conf.js`
+
+``` JavaScript
+reporters: [
+  // ...
+  'sabarivka'
+  // ...
+],
+coverageReporter: {
+    include: 'src/**/!(*.spec|*.module|environment*).ts',
+    exclude: 'src/main.ts',
+    // ...
+},
+```
