Beijing Btestsky is a national evaluation laboratory, with CNAS evaluation qualifications, specialized in software acceptance testing, and can be given an authoritative third-party test report; With more than 10 years of software evaluation experience, a complete set of complete, professional and comprehensive testing procedures and methods are developed in the field of acceptance test. This is an example of the ERP system for everyone to introduce.
1 The process, method and principle of ERP acceptance test.
1.1 ERP acceptance test.
The acceptance test of ERP system refers to the effectiveness of the system function test or the performance qualification test. It is the user-oriented, by the user, according to the project implementation of the technical requirements and functional requirements, in conjunction with the implementation of the relevant experts on the system of comprehensive testing. The acceptance test relates to whether the ERP system can succeed in the line, whether it is smooth to the maintenance period. Can quickly cut into business operations and improve the management of business management. ERP project acceptance includes phase acceptance and overall acceptance. ①The examination and acceptance of the stage. The general choice of timing is when the system is online, recorded more than a month of data. Ability to accurately export monthly reports. A month is just a small system cycle, in this period of time, the system is running smoothly, basically can reflect, if this month can not go through,. That means there are more problems in the operation of the system. ②Overall acceptance. It is based on the test acceptance of the stage. Do a comprehensive evaluation of the whole system to see if it encourages enterprises in management, management, management, management, management, business process, organizational structure, rules and regulations. The overall quality, enterprise competitiveness, enterprise image, scientific decision-making, information integration and processing, etc., some obvious improvement, improvement and innovation.
1.2The method and principle of ERP acceptance.
On the test method. Because of the particularity of acceptance stage, general black box test and configuration review mainly. With the automation test and special performance test, the ERP project implementation party together with the final user in the project expert group's leadership and coordination.
Of course, as a large comprehensive information project, the acceptance test must be careful. The participants must be in charge of the attitude of serious responsibility. At the time of acceptance, we must pay attention to the following principles: 1 is the acceptance test, always to confirm the ERP requirements specification and technical contract, to confirm whether the requirements are satisfied. The terms of the contract are carried out.2 is the acceptance test and unit test, the integration test is different. It is to verify the correctness of the software, not to find the software error-based. 3. The software errors found in the acceptance test should be classified. Until through acceptance.4 is a comprehensive and comprehensive design in the acceptance test. Can determine the function and performance of the software at the minimum time to meet the requirements.
2 The content and case design of ERP acceptance test.
The purpose of the ERP acceptance test is to verify that the ERP system implemented in the implementation of the contract is to meet the contract terms and function requirements of the signing of the contract. This paper combines the specific content of ERP acceptance test. This paper introduces the selection and design of test cases.
2.1 installation test.
The purpose of the installation test is to verify that the software can complete the installation in different configurations, and confirm whether it can run properly.
2.2 function test.
Functional testing is also a business test. It is the core content of the acceptance test, not just the test of the software function. At the same time, it is also a test of business process. The process of the implementation of the El system is the enterprise business process.
The main contents of ERP project function test and acceptance should be determined by different modules in the system, including system operation, business handling, all kinds of documents and statements. Mainly involved in the financial module, sales management module, inventory management module, procurement module, production planning module, and so on. In the acceptance process, it can be carried out by the department, and it is convenient to concentrate on the main issues.
In inventory management, the key is whether the flow of material and receiving is reasonable, and the efficiency of material and delivery is improved. All kinds of documents should be processed in accordance with the requirements.
In production management. It is mainly to assess whether the performance of the production plan is improved. The efficiency of production is improved. Including the maximum production capacity, production schedule rationality, production process optimization and so on.
2.3Interface test.
ERP interface should conform to current standards and user habits. The interface test should start with friendly, easy-to-operate, beautiful sex, layout rationality, classification science, title description accuracy and so on.
2.4 performance tests.
Performance test is the main test software running speed and the consumption of resources. By adjusting the hardware and software configuration of ERP, 2 network topology work site, data and service request to test the portability, operation rate, stability and reliability of the software. In general, the use of enterprise automation test tools such as WinRunner to assist the test, through the limit test to analyze the evaluation software performance.
2.5 document tests.
Document is an important part of software. It is also the important content of software quality assurance and system configuration management. ERP as a large-scale software. Covers all kinds of business of the enterprise. It should at least be required to define, develop design, test evaluation, project management, user application, etc. The document test is used to examine the integrity, accuracy, consistency, traceability and understanding of the document through the review.
2.6 other tests.
In addition to the above-mentioned tests, it is necessary to test the other features and needs of the system.
First, load pressure test. It mainly includes concurrent performance testing, fatigue strength test, large amount of data test and speed test. In general, automated technology is tested on the client, server, and network. Use case design. To be based on the real business, select a representative, key business operation as a test object.
Second, resume testing. By simulating hardware failure or intentionally causing software error, the detection system has the degree of damage to the data and the extent to which the data can be restored.
Third, safety test. Through illegal login, loophole scanning, simulated attack and other methods of detection system authentication mechanism, encryption mechanism, anti-virus function, and other safety protection strategies.
The acceptance of ERP project is a process of testing the effect of the project on the entire implementation stage. It is also an end of ERP project in the whole implementation stage, and it lays a solid foundation for the smooth operation of ERP system in the future.
