How to draw four boundary rounded corner in canvas for journeyapps zxing qr code scanner Java code? Here is the code that I used. Just a rectangle with no rounding. How to create a rounded rectangle with custom radius.

private float mLineRate = 0.1f;

private float mLineDepth =
        TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 5, getResources().getDisplayMetrics());

private int mLineColor = Color.rgb(50, 205, 50);

@Override public void onDraw (Canvas canvas){

        final Rect frame = framingRect;
        final Size previewSize = this.previewSize;

        final int width = getWidth();
        final int height = getHeight();

    paint.setColor(mLineColor);
    canvas.drawRect(frame.left, frame.top,frame.left + frame.width() * mLineRate,frame.top + mLineDepth, paint);
    canvas.drawRect(frame.left, frame.top, frame.left + mLineDepth, frame.top + frame.height() * mLineRate, paint);

    canvas.drawRect(frame.right - frame.width() * mLineRate, frame.top, frame.right, frame.top + mLineDepth, paint);
    canvas.drawRect(frame.right - mLineDepth, frame.top, frame.right, frame.top + frame.height() * mLineRate, paint);

    canvas.drawRect(frame.left,frame.bottom - mLineDepth,frame.left + frame.width() * mLineRate, frame.bottom, paint);
    canvas.drawRect(frame.left, frame.bottom - frame.height() * mLineRate, frame.left + mLineDepth, frame.bottom, paint);

    canvas.drawRect(frame.right - frame.width() * mLineRate, frame.bottom - mLineDepth, frame.right, frame.bottom, paint);
    canvas.drawRect(frame.right - mLineDepth, frame.bottom - frame.height() * mLineRate, frame.right, frame.bottom, paint);

}

Sidekiq workers can be directly invoked using Worker.new.perform which ensures they run in inline mode - simple Ruby method invocation. Not the prettiest solution but comes in handy for testing.

  expect {
    WorkerOne.new.perform(10, 15)
  }.to change(WorkerTwo.jobs, :size).by(1)
