1、 Test purpose

The function automation test plan is for XXX Automatic tools are used for system function test , Technology and implementation plan written to achieve the goal of automatic testing .

The main purpose of the document is to provide technical solutions for automated testing 、 Implementation content 、 Implementation steps , As well as the key technical implementation means .

2、 Terminology

Sahi： yes Tyto Software It's a business based open source Web Apply automated testing tools .Sahi Run as a proxy server , And through injection JavaScript To visit Web Elements in the page .Sahi Support HTTPS And independent of Web Site , Simple and compact but powerful . It is relative to the Selenium And other automated testing tools , In the dynamic ID Element search and implicit page waiting processing have certain advantages . choice Sahi Tools to achieve concrete Web Automated testing of the project is a good choice .

A functional test ： Functional test is also called correctness test , It checks whether the function of the software meets the specifications . Because correctness is the most important quality factor of software , So its test is also the most important .

automated testing ： Use the automated test tools provided by the business or the tools developed by yourself to test the target system . Tests performed automatically by the machine , Replace people to complete repetitive work , But it can't completely replace people . Automated testing requires testing tools , The participation of Test Engineers , Automated testing technology can be applied to all testing stages

Web Test background ： With Web The development of technology and Internet ,Web More and more application products , be based on Web The demand for page testing is increasing . At present, software all over the world is pursuing efficiency 、 In the context of agile development mode ,Web Automated testing has become a new wave of technology discussion and research upsurge . Because traditional manual testing is not only inefficient , And the test quality is limited by some emotions and moods of testers . If a tester tests these complicated and repetitive work with irritability , The quality of the test is worrying . What's more? , When this testing work involves the testing of globalization , The testing work of multilingual versions leads to the doubling of the testing workload , This is undoubtedly a huge test ！

checkpoint ： It is used to verify whether the script execution results meet expectations . Checkpoints can be established during recording , You can also create checkpoints after recording

                   

3、 Principles of implementation

It is impossible for tools to complete all the work in the process of functional automation testing , Tools are still an aid in the testing process . For tools, it is mainly to solve the repetitive tasks in the testing process . In addition, implement automated testing , There are also higher requirements for the tested system , Summarize the implementation principles of functional automation testing as follows ：

1) Use automated tools to test , The development of the tested system is required to be relatively stable , Less functional changes ;

2) Before recording the automated test script , The interface of the tested system is relatively stable ;

3) Functional test automation requires that the test data in the test data environment is relatively abundant , Meet the requirements of repeated regression tests ;

4) The version of the tested system is required to run stably , Fewer test aborts occur ;

5) Implement by stages and steps , Give priority to the system with relatively stable product functions ;

6) Perfect 、 Reusable data parameters 、 Script library is a long-term accumulation process .

4、 Advantages and disadvantages of implementing functional automated testing

Although there are many limitations in automatic and manual testing of functions , But it also has its advantages , With the development of automatic testing technology and tools , For the stable function of the product under test , Automated testing plays a more and more important role . Use Sahi It can speed up the whole test process , After the release of the product version , Test scripts can be reused for testing , say concretely ：

The advantages of automated testing ：

Improve test efficiency , Reduce the cost of testing ;

Manual labor with strong repeatability can be realized independently with automation ;

Rapid regression testing , Improve the speed and quality of new version release ;

Avoid mistakes easily made by manual testing , Such as ： Error testing , Leak test , More tests, etc ;

It's easy to implement concurrency testing ;

Test reusability , Reusing scripts and data is easy .

The disadvantages of automated testing ：

Standardized test management , Test requirements , The test case ;

Can't creatively find the defects that the test script has no design ;

High quality test cases ;

High quality automation test engineer ;

The requirements for the test environment are relatively strict ;

Changes in test requirements may cause a large number of test cases , Automatic test script modification 、 maintain .

                      

5、 Implementation scope and objectives

5.1 Scope of implementation

1) Tool range ： At present, consider Sahi、Excel And other tools ; Continuous integration tools will not be considered for the time being ;

2) System scope ： Locate the system in the basic test environment of the test center ;

3) Scope of the test phase ： Limited to late regression testing 、 And functional regression test after going online , Not included at present LT、 Function test part of internal test .

5.2 Implementation objectives

1. The function automatic test system should be able to complete the integration test 、 And the regression test of the function after the launch ;

2. The goal of the scheme is to complete the transaction test with and without interface , Transactions with interfaces support the following ：

a) Support character terminal interface ;

b) Support B/S Of Web Interface ;

c) Support C/S Of Windows Application interface ;

3. The function automation test scheme can test most of the current application systems ;

4. Realize automatic script recording 、 Automate script execution 、 Automated defect reporting and management .

5.3 Overall implementation strategy

1. First, choose the project and system suitable for automated testing from the current system ;

2. Secondly, determine the stage and timing of implementing functional automation testing ;

3. The third is to choose the functions and transactions suitable for the implementation of automated testing from the appropriate projects .

For specific implementation strategies, see Chapter 6 Section implementation management suggestions .
