Exploratory testing (ET) is an important testing method in the agile world. As a research tool, it is an important supplement to user story testing and automated regression sets. It does not have many practical test methods, techniques and tools, but it is a test thinking mode that all testers should master. Emphasize the subjective initiative of testers, abandon the complicated test plan and test case design process, and emphasize the timely change of test strategy when encountering problems.
The particularities of exploratory testing
Script testing: Design test cases first, and then execute testing according to the test cases.
Exploratory testomg：Do not design test cases in advance, and consider whether there is a problem elsewhere while performing the test. If you find a problem, focus on testing this part.
The advantages and disadvantages of ET
The tester spends more time to test some interesting or complicated situations
The tester can evaluate the system quickly
The test can be flexible
More interesting than script testing
It is hard to be adjusted
Unable to do a comprehensive test of the system
Rely on the knowledge and technology of the tester
Not applicable for a long test
The main purpose of the ET
Supplement of coverage
As an additional test after the classic script tests, it confirms whether the functionality tested by ET is covered by the script tests
Early detection of bugs
When executed as a smoke test, implement before a lengthy script test to prevent late rework
Reduce costs of test maintenance
During agile development, the cost of changing script tests is high, according exploration testing can reduce costs
The steps of ET
Establish a test plan
2 ways to implement exploratory testing
Split screen: each screen decides who is responsible
Based on the scene: select the favorite scene for testing
Reserve of product knowledge/bug knowledge
Understand the style, understand the product's past bugs
Make sure you're familiar with common testing scenarios
Knowledge of bug detection methods
Input value: maximum and minimum, decimal, maximum number of characters exceeded, greater than maximum, less than minimum, empty text, space, ellipses, null, non-existent time, special character, xss character.
Boundary: space boundary, time boundary.
Status: After initialization, the status of adding a large amount of data, etc.
Perform operations quickly, upload files in weak network environment, etc.
The key point is short-term concentration test
If you need a long time, try to control it within 30 min
No detailed log
When a bug is found, record it
Summarize test results and report
Who is responsible for which picture/which scene
Arrange the detailed reproduction steps of the bug and submit bugs
If it cannot be reproduced, report it as risk
Report other concerns
Problems such as user medical examination improvement
