How to automate high voltage testing on desktop computers

Hello, I'm here to answer for you:

Using IQultra's C++ software application programming interface (API), users can quickly and easily develop a variety of automated test programs.

LitePoint's new IQNXN MIMO R&D Test System is a modular Mimo R&D test solution, with each module having its own Vector Signal Analyzer (VSA) and Vector Signal Generator (VSG).

If I can't help you, please keep asking.

1.Test automation is similar to the process of software development.

Recording Playback scripts are not developed in a way that can handle all the needs of automated testing, so testers need to have the necessary development knowledge and coding knowledge.

2.Test automation is a long-term process.

First of all, automated testing cannot be expected to find many bugs in the short term, and automated testing can only show its value after multiple runs over a long period of time. Secondly, don't think that as long as you buy tools, record some scripts, and then you can rest easy and watch the automated test achieve the desired effect, you need to consider the maintenance cost of automated test scripts, as the number of maintenance tools for test scripts will increase dramatically with the increase and modification of the functions of the application being tested.

3.Resources to ensure test automation, including people and skills.

It is best to have a dedicated automated test engineer to ensure that the test automation continues and goes smoothly, and the automated test engineer needs to be responsible for the project test automation, design the test framework and script structure, solve the development problems of various test scripts, and ensure that the automated test can be planned, designed and developed and maintained in an orderly manner.

4.Automate testing step by step.

Don't start with a big idea of automation, which is often unachievable, start small, first familiarize yourself with the basic skills of tools and automated testing, and then, integrate resources to start implementing some basic automated test cases, such as: smoke test type automated test scripts, first implement those easy to implement, and relatively stable functional modules of automated testing, and then consider gradually expanding and supplementing other relatively difficult to implement, or relatively unstable functional modules.

5.Ensure the maturity of the testing process.

If the capability maturity of the testing process and project management process of the software enterprise is relatively low, the success rate of realizing automated testing is also relatively low. For example: Are the tests done independently? Is there configuration management?

How well can you control your schedule? If the maturity of all aspects of capability is relatively poor, do not blindly introduce test automation.

Automated testing should look like this:

Automation as a service should be a service, and all testers and developers should be able to run automation on their own.

The results of automated tests should be automatically analyzed and take up very little time.

The success rate of automated testing should be high (e.g. more than 95%)

Automation should be written once and run many times, why do you spend so much time changing automation**?

OK. The general functional testing is based on a graphical interface, and the most popular tools in the industry are QTP, WinRunner, IBM Rational Robot, Rational Robot.

Open source tools: Watir, Watin

Specific methods:1Recording scripts, reinforcements, playback.

2.Handwritten scripts, playback.

Addendum: Only a few companies such as Mercury (HP), IBM, etc., write the test software. Generally, companies do not write test software, and the so-called self-writing automation scripts means that they use commonly used programming languages to write ** for testing software.

At present, automated testing is mainly based on testing software.

In today's competitive market, where every product has similar features, how to make sure your product is fully tested. Coverage analysis is a simple way to determine if your tests are complete and capable of spanning the entire lifecycle, from individual developer testing to final release testing.

Test integrity is assessed by **coverage.

Benefits of Coverage Analysis.

1. Coverage is the only reliable indicator for assessing test integrity.

2. The coverage analysis is especially for high-security industry applications, such as: military, aerospace, rail transit and automotive electronics.

Ensure system test integrity with coverage analysis.

System testing, also known as functional testing, is the process of ensuring that the application is correct when used by the end user. This type of testing is either done manually or by automated scripts. All are subject to system testing prior to release.

The challenge of system testing is how to ensure test integrity. Eventually, the team will develop a testing process to verify that the application meets the requirements or meets the user documentation.

The only way to ensure the integrity of the system testing is to collect and analyze the coverage data during the testing process. Both the DT10 and Vectorcast Cover allow users to easily collect coverage during system testing, including coverage data performed on the target board.
