Bugs found in Grainger for Android
Grainger is a leading supplier of industrial wares, MRO equipment, tools, and materials to businesses and institutions across North America, Japan, and Europe. Apart from a robust e-commerce platform hosting more than one million products, Grainger developed a mobile app to make the products even more accessible to consumers. The app allows the users to quickly find the needed item by applying filters, check if the product is available at the nearby branch, scan the barcode to instantly add the product from a catalog to a cart, and keep track of all the orders. On top of that, Grainger for Android offers such fancy features as voice search, enhanced search by image, guest checkout, and order tracker with detailed shipment and pick-up information.
Having tested hundreds of Android e-commerce apps, we know what areas to check in the first place to find vulnerabilities and mistakes. Here are some Grainger bugs we managed to uncover during our express manual testing.

The Grainger app has a number of attractive features, such as a well-filtered product search, instant payment, as well as the ability to create lists with folders, which is super convenient for basic inventory management. Nevertheless, I wish the sign-in process was smoother, and I also managed to catch a couple of bugs. They are not critical to the app’s overall functioning, yet they may be annoying, especially for first-time users, like reloading the app just to create a new folder or confusing error messages. Inaccuracies like this though can be easily prevented by manual QA engineers.
