I found that whether it is a new tester who has just entered the workplace or an old man with several years of testing experience, for the test case design, if he has not been in contact with tested software products, he will basically not be able to answer when asked how to test. In the final analysis, the accumulation of test thinking is not enough.
I have compiled an article on how to write test cases and cultivate test thinking before. I suggest that the use cases are weak and take a good look.
In view of the fact that many small partners are looking for jobs at present, we simply sort out the use case design questions that have been feedback recently to assist everyone in their high-paying job hunting!
Test Case Design Questions
01. Use case design questions - self-service shopping APP
Answer arrangement:
Assuming buy 2 get 1 free, you only need to scan the code for 2 items, and the purchase list will automatically add the gift item
Assuming that the same item can only enjoy a single discount, for example, if it is buy 2 get 1 free, there is no discounted price
1 Normal shopping process verification
Scan codes for regular-priced products, direct discounted products, and buy 2 get 1 free products, and add purchases
1) Add items and check whether the read prices are correct:
a. Scan the code to automatically fill the barcode box for regular-priced products and read the correct price
b. Buy 2 get 1 free. Scan the QR code for 2 items to automatically add 1 free item (the gift price is 0, and the other 2 items are at the regular price)
c. Directly discount products, manually enter the barcode box, and read the discounted price
2) Click Settlement, select APP account balance payment, whether to pay normally
3) Whether the password for opening the gate is automatically generated after the payment is successful, and the door can be opened by swiping the code normally
2 Supplements to other normal shopping processes
1) Scan the QR code to add multiple buy 2 get 1 free items, whether the gift items are normally displayed in the purchase list and the price is 0; choose to pay with WeChat to check whether the payment is normal, and generate a password to open the gate to open the door normally
2) Scan the QR code to add multiple discounted products, whether the discounted price is displayed normally; choose to pay with Alipay, whether it is normal to pay, and generate a password to open the gate to open the door normally
3) Test the situation where the added product exceeds 1 page (generally 10 products per page)
4) Delete the scanned product, whether it is deleted normally, and the price subtotal is correct
5) Reduce the quantity of scanned products, whether the quantity is reduced normally, and the price subtotal is correct
3 Verification of other situations
1) Click the scan function, manually enter the wrong barcode in the barcode box, whether the app is processing normally
2) The number of products added exceeds the current inventory of the supermarket, whether the app prompts normally
3) If you frequently click on the settlement function multiple times, does the app remind you that you cannot submit operations frequently?
4) The price of purchased goods exceeds the app account balance/WeChat balance/Alipay balance
5) The generated gate opening password has been scanned and used, whether it can be reused
6) For the failure of normal payment and the failure to swipe the code to leave, whether the app has timely alarm processing
02. Use case design questions - stock software
Please design a test plan for the business functions in the following interface:
Tip: It needs to be refined to test scenarios and test points
Answer arrangement:
Scenario for buying stocks:
1. The operation of buying stocks is normal. After the purchase, whether the stocks are normally displayed and recorded, and whether the amount is deducted normally
2. Enter the first few digits of the stock code, whether it can be automatically associated; whether the shareholder code in the drop-down box is displayed completely, select the first, last, and middle selection test of the shareholder code in the drop-down box
3. After entering the stock code, the stock code can be automatically associated, and it can also support input
4. The available funds normally display the current available funds, and you can enter positive amounts, 0, negative amounts, and more than the current available funds
5. Select limit order for order type, buy price lower/higher than market price, whether to buy automatically
6. The test of the boundary value of the buying price, such as limit-down and limit-up price boundaries
7. Whether the maximum quantity is calculated correctly, available funds/buying price
8. Select by quantity: the purchase quantity is less than or equal to the boundary value test of the maximum quantity that can be purchased, and it is 0, negative, or exceeds the maximum purchase quantity
9. Select by amount: the purchase amount is less than or equal to the limit value test of the maximum purchase amount, which is 0, negative, or exceeds the maximum purchase amount
10. Check all, 1/2, 1/3, and 1/4 respectively to verify whether the purchase is normal
11. Verification of the clearing function, whether the input content of buying stocks is cleared normally
Single Interface Test Scenario 1 Solution
1. Buy stocks with more than 1 page (according to 1 page, 10 items) to check the stock display
2. When buying too many stocks, select the first, last, and middle one according to the boundary value, and check whether the value of each field of each stock is displayed correctly, especially pay attention to the amount-related fields
3. When the stock price fluctuates, pay attention to whether the stock market value, profit and loss, profit and loss ratio, etc. are correct
4. When the stock is sold and purchased, whether the total amount of securities and the available quantity are correct
5. Whether the keyword query function and the sorting function of the stock query are correct
Data display correctness verification
Select different stock codes to check whether the data in the buy, sell, cancel order, transaction, and position views are displayed normally
Carry out different business operation simulations of stocks, and check whether the data is displayed normally
03. Smart door handle, how to design test cases?
The direction is the same. From the perspective of function, interface, compatibility, ease of use, security, performance, etc., during the interview, first answer based on your understanding of electronic locks.
The functions can be : whether fingerprint unlocking, password unlocking, whether there is an upper limit for the set fingerprint and password, whether the set password has strength verification, whether the key can be unlocked when there is no power, how many times the password is entered incorrectly, the electronic lock will be locked and whether It is bound to the mobile app to notify illegal unlocking warnings, etc.
