Test cases for in-app search, filters and sort

1. Tap the search bar on the home screen
2. Type the full name of a known in-stock product and tap Search
3. Tap the matching result

Expected: The product appears among the first results with its image, name and price, and tapping it opens that product's page with the same price.

1. Search for a broad term such as shampoo or rice
2. Scroll through the first two screens of results

Expected: The top results are that kind of product, and items that only mention the word in passing are not ranked above the products themselves.

1. Type the first three letters of a popular product, such as bis
2. Watch the suggestion list as you type each letter
3. Tap one of the suggestions

Expected: Suggestions appear within a moment and contain what you typed, and tapping one runs that exact search and shows its results.

1. Search for shirts and open Filters
2. Set a price range of ₹500 to ₹1,000 and select size M
3. Apply and scroll through all results
4. Tap Clear all

Expected: Every result is size M with a selling price inside the range, active filters show as chips with an updated count, and Clear all restores the original results.

1. Search for a dish that comes in veg and non-veg versions, such as biryani
2. Turn on the Veg only filter
3. Scroll to the end of the results and open a few items
4. Search for another dish without touching the filter

Expected: Every result, including those loaded further down, carries the vegetarian mark. On the new search the filter chip shows whether Veg only is still on, and the results match it.

1. Search for headphones and choose Sort by price: low to high
2. Note the prices of the first twenty results
3. Switch to high to low

1. Tap the microphone icon in the search bar and allow microphone access
2. Say a product name clearly, such as basmati rice
3. Wait for the results

Expected: The app shows that it is listening, puts the recognised words in the search box where you can edit them, and shows results for those words.

Why a real phone: Needs a real microphone, real speech and the phone's own speech recogniser.

1. Search for shampo, then tomatoe, then sandels
2. Look at the top results and any message above them

Expected: Each search shows the intended products, with a note such as Showing results for shampoo and an option to search the exact spelling instead.

1. Search for salt & pepper, 100% cotton, kids' shoes and "red" saree
2. Search for an emoji on its own, such as 🍕
3. Search for a query that ends in a backslash or a percent sign

Expected: The app never crashes or shows a server error. Each query is shown back exactly as typed, with relevant results or the normal no-results screen.

1. Tap the search bar and press the keyboard's Search key without typing
2. Type only spaces and press Search

Expected: No search runs and no No results screen appears. The app keeps showing recent or popular searches.

1. Copy a paragraph of about 500 characters from a notes app
2. Paste it into the search bar and press Search

Expected: The app trims the text to its input limit or searches it, without freezing, crashing or pushing the layout off screen.

1. Search for a nonsense word such as qzxvbn
2. Read the screen and tap any suggestion offered

Expected: A no-results message repeats the query and offers a way forward, such as spelling tips or popular items, instead of a blank screen.

1. Search for shoes and filter to a size and colour with no stock

Expected: The app says no items match these filters and offers to remove the last filter or clear all, rather than the generic no-results message.

1. Search for atta, then aata, then aatta
2. Search for paneer, then panir

Expected: The Hindi query returns the same kind of products as atta, and the query is shown in Devanagari without broken characters.

2. Search for jeera, then cumin

Expected: Each name brings the same vegetable or spice to the top of the results.

1. Search for t-shirt, tshirt, t shirt and tshirts

Expected: All four return largely the same top results, and none of them falls back to no results.

1. Search for atta 5kg, then 5 kg atta, then atta 5 kilo

Expected: The results update for the new location, the item is hidden or marked unavailable, and the PIN code shown on the results screen is the one you picked.

1. Switch the phone to 2G, or stand where the signal is weak
2. Search for a common product
3. Wait, then tap Retry if it is offered

Expected: A loading state shows while waiting, results become usable before every image has loaded, and a timeout ends in a retry message rather than an endless spinner.

Why a real phone: Real Jio, Airtel or Vi signal loss behaves unlike the emulator's steady throttling.

1. On a slow mobile connection, type shoes, delete it and quickly type sandals
2. Press Search and watch the suggestions and results for a few seconds

Expected: Suggestions and results end up matching sandals. Late responses for the earlier text do not replace them.

Why a real phone: Uneven real-network latency makes older responses arrive after newer ones.

1. Search for a broad term on mobile data and scroll partway down
2. Enter a lift or a metro dead zone and keep scrolling
3. Return to coverage and keep scrolling

Expected: Loaded results stay visible, the end of the list shows a retry prompt, and loading resumes after reconnecting without duplicate or missing items.

Why a real phone: Lift and metro dead zones stall requests in ways aeroplane mode does not.

1. Tap the microphone icon and start speaking
2. Receive an incoming call, answer it and end it
3. Return to the app

Expected: Listening stops when the call arrives, nothing half-heard is searched, and the search screen is ready for a new voice or typed query.

Why a real phone: A real call takes over the microphone and audio focus mid-recognition.

1. On a 3–4 GB RAM phone, search, apply two filters and sort by price
2. Use the camera and two heavy apps for a few minutes
3. Return to the shopping app from recent apps

Expected: The app either restores the query, filters and sort or opens a clean search screen. It does not crash or show filter chips that do not match the results.

Why a real phone: Only real low-RAM phones kill background apps this aggressively.

1. On a 3–4 GB RAM Android phone, search for a broad term such as kurta
2. Fling quickly through about 300 results
3. Tap Back to top, then open a result

Expected: Scrolling stays responsive with no crash or restart, images fill in without long blank gaps, and the opened product matches the tapped card.

Why a real phone: Memory limits and slow storage on budget hardware cause crashes that emulators hide.

1. Type a query with the Samsung keyboard on a Samsung phone
2. Press the keyboard's Search or Enter key
3. Repeat with the preinstalled keyboard on a Xiaomi or Vivo phone

Expected: On each keyboard the key runs the search and closes the keyboard, rather than adding a new line or doing nothing.

Why a real phone: Preinstalled OEM keyboards send different key actions from the emulator's keyboard.

1. Connect Bluetooth earphones to the phone
2. Tap the microphone icon and say a product name

Expected: The app picks up your voice through the earphones or the phone's microphone and shows results. It does not hang on the listening screen.

Why a real phone: Bluetooth earphones reroute the microphone, which emulators do not reproduce.

1. Tap the microphone icon and choose Don't allow
2. Tap the microphone icon again
3. Type a query in the search box

Expected: The app explains why it needs the microphone and points to settings instead of failing silently, and typed search keeps working.

1. Log in as account A and search for three distinct terms
2. Log out, then log in as account B on the same phone
3. Tap the empty search bar

Expected: Account B sees none of account A's recent searches, and no suggestions based on them.

1. Search for <b>bold</b>, then for <script>test</script>
2. Look at the search box, the no-results message and recent searches

Expected: The text is shown literally everywhere, no formatting or script runs, and no error page appears.

1. Turn on TalkBack and move focus to the search bar
2. Type a query and move through the suggestions
3. Run the search and move to the filter chips and the first result

Expected: The search bar and microphone have clear labels, the result count is announced, filter chips read as selected or not, and each result reads its name and price.

1. Set font size and display size to the largest in phone settings
2. Search for a product and open the filter and sort panels

Expected: Result names wrap instead of overlapping prices, filter labels are not cut off, and the Apply button stays visible.

1. Set the voice input language to Hindi
2. In a moderately noisy room, tap the microphone and say do kilo aloo
3. Switch voice input to English and say basmati chawal

Expected: The recognised text appears in the search box in Devanagari or Roman script, and the results show potatoes or basmati rice rather than no results.

Why a real phone: Real speech, accents and room noise affect recognition in ways recordings cannot.

1. Switch the app language to Hindi
2. Search for a product priced above ₹1,00,000, such as a large television
3. Open filters, sort and the no-results screen

Expected: Labels and messages are in Hindi without truncation, and prices use Indian grouping such as ₹1,05,990 on cards and in the price filter.
