1. Definition of Automation
With the help of test tools, in accordance with test specifications, partial or full replacement of manual tests can improve the effectiveness of tests.
Note: The test does not need to test all the functions of the software, such as the help of many software.
2. Features
Simulate manual operation: The software replaces manual operation and operates the interface.
3. Features of automated testing
- Optimize cost
- reliable
- fast
- Reusable
Fourth, automation advantage
- Repeatability
- Programmable: It can be programmed and the format can be standardized
- Reliable: not emotional and stable
- Improve test accuracy
- Improve the utilization of test resources: human resources, time resources, etc.
Five, the difference between manual testing and automated testing
1) Many defects found in manual testing: Because people are intelligent, they can consciously judge more problems and phenomena and find more defects.
2) The quality of manual testing is higher: because manual testing can find more unplanned defects.
3) Automated testing and development are closer: because automated testing requires programming code.
4) The respective limitations of the two: In comparison with manual testing, work efficiency is low, and it is easy to be emotional and lead to unstable work content; automated testing cannot think like people.
6. Classification of automated test software
function test:
- UFT: Interface layer, payment
- Selenium: free, web automation for writing code, small installation package
Performance Testing:
- loadrunner: chargeable, powerful, 50% usage rate
- rational robot
- jmeter
Test management tools:
- Zen Tao & Jira: High cost
- Interface testing tool: postman
- Self-developed tools: meet business needs and have strong pertinence
- Open source testing tools: low cost, flexibility, and poor ease of use
- Commercial tools: powerful, easy-to-use, expensive, comprehensive consideration of interactive interface
Seven, automated workflow
Automated test decision -> test tool acquisition -> automated test introduction -> test plan design and development (script) (the most important) -> test execution and management (the most troublesome) -> test review and evaluation
8. Factors considered in automated testing
1) Project impact: automated testing has a positive effect on project accuracy and coverage risk, making development more agile
2) Complexity: Is it easy to realize automation, including data and other environmental impacts
3) Time: how long does it take to realize the automated test
4) Requirements: early requirements and code stability
5) Workload: Whether the code is relatively stable and whether the functional characteristics will evolve
6) Coverage: Can the key features and functions of the program be covered?
7) Resources: test human resources, hardware resources
8) Automated execution: Do you have time and skills to run
Nine, the application of automated testing
1) Regression test: perform previous tests when developing a new version of the software
2) More and more frequent tests
3) Work that cannot be achieved by manual testing
4) Cross-platform testing: compatibility testing of web testing
5) Repetitive operations
Not applicable:
1) Unstable software version
2) Design and test the interaction with physical equipment
3) The test result is easier to pass the test of human judgment
Ten, test tool selection
1) Buy the right ones, not the expensive ones
2) Choose mainstream testing tools
3) Introduce testing tools in stages and gradually
4) Choose products with perfect technical support
5) If you need multiple tools, try to choose a company product
