Introduction

1. Try to understand whether to put more effort on testing or to solve problems faster in production, and weigh the two.

two。 A failed test does not directly affect the user, but once the product starts working, it begins to do so.

Testing should always keep the end-user's perspective in mind to ensure that the software can be accepted by some users. However, how to test web services that are not directly customer-oriented, especially how to test performance in a meaningful way? This article outlines some performance testing methods that have been developed and proven to be effective at HERE. HERE is a leading location cloud computing company. Since the performance of web services has been hosted on HERE's cloud platform and bound according to service layer protocols, we have thoroughly tested the performance of web services through continuous integration and delivery.

Web services are software components that use standards-based Web technologies including HTTP and XML-based messaging to communicate with other components. They provide an interface to describe the set of operations. The Restful web service communicates with stateless operations. Web services allow applications to communicate with each other without the need for time-consuming custom coding. And because communications rely on industry-standard protocols, they do not rely on any operating system or programming language. However, distribution and loose coupling also make testing web services challenging.

Testing method

Tests should be created with the relevant knowledge of the end user so that the tests are effective and risk-based. Because of these factors, as well as version technologies such as Canary versions and feature switching, the line between test runs before version releases and released software has become blurred. For example, the Ahand B test has become popular because it can determine the impact of new features or changes in the product on the user experience. This article raises the question of whether this idea can also be applied to performance testing, and how to base performance testing (RESTful) web services on a meaningful and realistic usage scenario before the release.

Acceptance test

Acceptance tests are based on the use of real-world cases to discuss requirements and tests performed according to those acceptance criteria. In this way, tests can be used to create executable requirements specifications, and software can be created based on those real-world cases.

Therefore, an acceptance test can be seen as a description of the characteristics of a software product, usually as an example or usage scenario. In reality, however, the use of software changes over time, so outdated test data can lead to risks. If the test data is out of date, the test must be updated.

Acceptance tests can be written for the web server as well as for the front end.
