1-Introduction: nowadays the use of tools has become as essential to automate many processes. Test flow specifically is a very important flow in software development. The investigation of the use of tools became indispensable to improve the quality and efficiency of this flow. During the investigation will be to know the importance of the tool to use, as well as its operation, through real-life examples of tests performed to a module. 2 – Tool JMeter the JMeter is a free tool, it is also a Java tool that allows performance testing and functional testing on Web applications.

It is a tool of burden to carry out simulations on any Software resource. JMeter a Java tool within the project of Jakarta, that allows to perform performance testing and functional testing of web applications and databases. There are a number of tools for free testing and payment (LoadRunner), but JMeter stands out for its versatility, stability, and for being of use free of charge. JMeter allows classic web testing, but also allows you to perform test FTP, JDBC, JNDI, LDAP, SOAP/XML-RPC and Web Service (Beta). Also lets you run tests distributed between different computers to perform performance testing. The JMeter shows the results of tests on a wide variety of reports and graphs. Also facilitates a rapid detection of existing bottlenecks due to excessive response time.

All these tools can be used to make efficiency under intensive load tests, however there are some that have advantages with respect to the others, so they are more optimal to use during the tests in question. In an application it is vitally important to employ some time prepare efficiency under load and stress tests, before being delivered. The time spent is recovered by far, since the potential side effects were detected and can check if this new functionality supports the amount of concurrent users that are specified in the requirements.
