Ten negative test cases in software testing

1, implanted single quotation marks. includes a variety of special characters and so on.

2. Data entry that must be entered. The data entry specified in the instruction manual must be tested for each input, preferably at the front end, and for mandatory identifiers, if there are no prompts when filling out

3, field type test. each of the tests on the screen is indicated to have a specific type of field,(numeric fields should not allow characters or special characters, date Type fields should allow for a correct date, and so on). Prompt is reasonable.

4, field length test. prevent user input more than the allowable range of words transmitting because the user has entered too many characters to give the error message more elegant. For fields that have no limit on length, there is an error in testing the Infinity input.

5, the digital boundary test.

6, the number of constraint testing. for numeric data entries that do not have a specific boundary limit, test these restrictions to ensure that no numeric overflow errors occur.

7, date boundary test.

8, the validity of the date . for date fields, ensure that invalid dates are not allowed

9. Web session testing. The application should ensure that there is a valid login in the session before opening a page of the application.

10, the performance of the change.
