An automation test engineer converts manual test processes into automated ones, writes software code, and evaluates the effectiveness of automated test protocols. They work closely with test designers and application developers and are responsible for programming automated scripts.
An automation test engineer determines the best way to convert a manual test process into an automated test process and employs various automation technologies to meet test goals. He or she typically evaluates the effectiveness of automated test protocols and systems designed to test the various functions of a product or manufacturing process. The software code needed to run the test and process the results is written and coded by the automation test engineer. Duties often depend on the specific testing phases they oversee.
In the unit test phase, the automation test engineer enters application code designed to accept and process test commands on a machine. Code is usually tested for repeatability so that it can be tested periodically without interruption. Once the code is OK, it is usually distributed to machines on the production line.
The function and system testing phase involves a set of commands that are generally designed to increase testing speed. The engineer often tweaks the software code to improve the efficiency of the test preparation process. In addition, the automated test engineer can create test cases to prepare the machine for testing.
After function and system testing, the engineer performs an acceptance test to verify that the code will work as designed. The acceptance test is usually modified after the test results to improve effectiveness. If improvements are needed, they are usually conveyed to the designer or test lead.
The test lead typically ensures that a system’s automation goals are met, while the automation test engineer measures, implements, and tests a solution. An automation engineer must also work closely with the test designer to determine the automation requirements for a specific project. Using this input as a guide, the automation engineer determines how the automated system should be built. The automation engineer must also work closely with the application developer to address implementation challenges.
Automation test engineers are often required to program automated scripts in the language of the software tools used by the company. In many situations, logs and files created by automation tools need to be interpreted and passed to the manual test engineer. In addition, the engineer is usually required to maintain test scripts for use in other projects.
