This article introduces the relevant knowledge of "what is the method of Android automated testing". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Automated testing

Automated testing refers to the automation of software testing, running the application or system in a preset state, including normal and abnormal conditions, and finally evaluating the running results. The process of transforming human-driven testing behavior into machine execution.

The automated testing framework can generally be divided into two levels, the upper layer is to manage the development, execution and maintenance of the entire automated test, in a relatively large project, it plays an important role, it can manage the whole automated test, including the order of automated test case execution, the maintenance of test scripts, and the centralized management of test cases, test reports and test tasks. The lower layer is mainly the development of test scripts, make full use of relevant test tools, build test drivers, and complete the test business logic.

Automated testing method

(1) Test objects: UI, interface, code

① UI automation: use cases maintain a large number of pages with strong correlation, and must be involved in UI testing in the later stage, which is suitable for projects with small interface changes.

② interface automation: it can be involved in the early stage of the product with small use case maintenance, small page correlation and suitable for projects with small interface changes and frequent interface changes.

(2) testing process: system testing, integration testing, unit testing.

(3) Executive: testers and developers can implement automated testing at any stage in the whole testing process. Testers generally conduct automated testing and integration testing during system testing, and most of them are automatically built and deployed in the integrated testing phase. and automated unit tests for smoke testing can be tested at the code level, static code checks can be performed, or unit test cases can be executed Typical frameworks such as junit, jmock, etc., are mostly implemented by developers.

1. Advantages of automated testing

Reducing the manpower input of large-scale system regression testing caused by change or multi-phase development may be the most important task of automated testing, especially when the program is modified more frequently, the effect is very obvious. automated testing has more manpower investment in the early stage, but after entering the maintenance period in the later stage, it can save a lot of manpower. In the later stage of manual testing, we need to increase a lot of manpower for regression testing to reduce the time of repeated testing, to achieve rapid regression testing to create an excellent and reliable testing process, to reduce human errors, to run more and more tedious tests, to perform some manual tests that are difficult or impossible, and to make better use of resources.

How to implement automated testing

Applicable objects for automated testing

Prerequisites for implementing automated testing: requirements do not change frequently, project cycle is long enough, and automated test scripts can be reused.

For projects with frequent changes in ① requirements, automation scripts can not be reused, maintenance costs are too high, and the ratio of performance to price is low.

② project cycle is short, automatic script preparation after the completion of the use of not many times, low performance-to-price ratio

③ interactive projects, projects that require human intervention, automation can not be implemented

two。 Projects suitable for automation:

① product project. For the product-based project, the new version is improved on the basis of the old version, but the new and old functions of the project must be tested repeatedly. Regression testing is the strength of automated testing, it is a good way to verify whether you have introduced a new defect, whether the old defect has been modified. To some extent, automated testing tools can be called regression testing tools.

② is tested mechanically and frequently. You need to enter the same amount of data each time, and it takes a long period to run in a project.

3. How to implement automated testing

(1) Analysis: grasp the logic of the system as a whole and analyze the core architecture of the system.

(2) Design: design test cases, which should be clear and clear enough, with wide coverage and precision.

(3) implementation: to implement the script, there are two requirements: one is assertion, the other is reasonable use of parameterization.

(4) execution: executing the script is far from as simple as we thought. We need to carefully analyze the reasons for the exceptions in the execution of the script.

(5) Summary: the analysis of test results and the summary of test process are the key to automatic testing.

(6) maintenance: the maintenance of automated test scripts is a problem that is difficult to solve but must be solved.

(7) Analysis: deeply analyze the coverage risk of automation use cases and the cost of script maintenance in the process of automation testing.

4. The reasons for the failure of automated test implementation

one

(1) the expectation is too high. Just as managers require complete testing, it is also an unrealistic requirement to expect 100% test automation.

(2) do not have a clear understanding of benefits and costs. Apart from the development or purchase costs and training costs of tools, the cost of automated testing should also include two parts (test preparation costs are also implied in the actual cost):

Cost = realization cost + operation and maintenance cost

The benefits of automated testing are determined by the number of times the test script is repeated, or by the utilization of the automated test script.
