Question

使用以下配置，在更改mShareLoadingPB.setVisibility(View.VISIBLE); Log.d("ShareImageTask", "onPreExecute: " + System.currentTimeMillis()); Observable.fromCallable(() -> { Uri bmpUri = null; try { // Use methods on Context to access package-specific directories on external storage. // This way, you don't need to request external read/write permission. File file = new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png"); FileOutputStream out = new FileOutputStream(file); resource.compress(Bitmap.CompressFormat.JPEG, 90, out); out.close(); // wrap File object into a content provider. NOTE: authority here should match authority in manifest declaration bmpUri = ImageFileProvider.getUriForFile(PhotoFullScreenActivity.this, getApplicationContext().getPackageName() + ".fileprovider", file); // use this version for API >= 24 } catch (IOException e) { e.printStackTrace(); mShareLoadingPB.setVisibility(View.GONE); } return bmpUri; }) .subscribeOn(Schedulers.newThread()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(new DefaultObserver<Uri>() { @Override public void onNext(Uri uri) { mShareLoadingPB.setVisibility(View.GONE); mShareIntent = new Intent(); mShareIntent.setAction(Intent.ACTION_SEND); mShareIntent.putExtra(Intent.EXTRA_STREAM, uri); mShareIntent.setType("image/*"); startActivity(Intent.createChooser(mShareIntent, "Share image")); } @Override public void onError(Throwable e) { Log.e("Error","Error"); } @Override public void onComplete() { } }); cli选项时，覆盖率报告会中断。我尝试设置testMatch选项，但这也不能解决问题。

./ src / sum.js

collectCoverageFrom './src/*.js'

./ test / sum.js

function sum(a, b) {
    return a + b;
}
module.exports = sum;

package.json

const sum = require('../src/sum');

test('adds 1 + 2 to equal 3', () => {
    expect(sum(1, 2)).toBe(3);
});

设置testRegex参数：

jest --testRegex='./test/.*\.js$' --coverage --coverageDirectory './test-coverage'

现在输出看起来像这样：

PASS  test/sum.js
✓ adds 1 + 2 to equal 3 (3ms)

为什么在更改testMatch正则表达式时Jest覆盖率报告会中断？
