Pytest information

What is Pytest?

Pytest is a popular testing framework for Python that allows developers to write simple as well as scalable test cases. It is widely used for unit testing, functional testing, and integration testing in Python projects. Pytest makes it easy to write small tests, yet it scales to support complex functional testing for applications and libraries. Its rich plugin architecture and simple syntax make it a preferred choice for many Python developers.

What are the key skills and qualifications needed to thrive as a Pytest automation engineer?

To excel as a Pytest Automation Engineer, you need strong programming skills in Python, a solid understanding of software testing principles, and experience with test automation frameworks. Familiarity with Pytest, continuous integration tools (like Jenkins), and version control systems (such as Git) is typically required, along with relevant certifications in software testing or Python development. Attention to detail, analytical thinking, and effective communication help you identify issues quickly and collaborate across development teams. These abilities are crucial for ensuring software quality, speeding up release cycles, and maintaining robust, scalable test systems.

How does a Pytest automation engineer typically collaborate with developers and QA teams during a software release cycle?

As a Pytest automation engineer, you will often work closely with both developers and QA professionals throughout the software release cycle. You’ll be responsible for creating and maintaining test suites using Pytest, reviewing code changes, and ensuring that automated tests cover new features or bug fixes. Regular communication is essential, as you’ll need to report test results, discuss defects, and coordinate on test coverage or continuous integration setup. This collaborative approach helps maintain high code quality and smooth releases.

What is the difference between Pytest vs Selenium Tester?

AspectPytestSelenium Tester
Primary FocusAutomated testing framework for Python codeWeb application testing using browser automation
Required SkillsPython programming, testing frameworksWeb technologies, Selenium WebDriver, scripting
Work EnvironmentSoftware development, QA teams, CI/CD pipelinesWeb testing, QA teams, browser environments
Common CertificationsPython certifications, testing certificationsSelenium certifications, QA certifications

Pytest is a Python testing framework used primarily for unit and integration testing of Python applications. Selenium Tester specializes in automating web browsers to test web applications. While both roles involve testing, Pytest focuses on code-level testing within Python projects, whereas Selenium Testers focus on browser-based testing of web interfaces. Understanding these differences helps teams assign the right tools and skills for their testing needs.

Job description

Test Automation Engineering Intern 

Redwood Energy is building some of the fastest, lowest-cost energy storage in the U.S. from both new battery modules and second-life EV packs. Second-life hardware arrives with a history - different chemistries, capacities, and states of health - and every unit has to be proven safe and reliable before it ships. That proof comes from test: the automated systems that exercise the firmware and electronics inside our products and decide whether they're ready for the field. 

Our test engineering team builds those systems - the test stands on the production floor, the hardware-in-the-loop benches that validate firmware releases, and the CI pipelines that tie them together. As a Test Automation Engineering Intern, you'll work alongside our engineers building the next generation of this test capability. You'll write Python that drives real instruments and real battery hardware, help bring up new test stands from the bench up, and debug failures where the root cause could live in the test code, the firmware, or the unit under test. This is a great opportunity to apply what you've learned in coursework to production test systems, with mentorship from experienced engineers along the way. 

Responsibilities will include:  

  • Test Automation: Write and maintain Python test automation for firmware and hardware validation, using pytest and our internal test frameworks. 
  • Instrument Control: Develop drivers and tooling for programmable power supplies, electronic loads, data acquisition, and switching hardware over protocols like SCPI, CAN, and Modbus. 
  • Test Stand Bring-Up: Help bring up new test stands - from fixtures and wiring through the software that sequences them - as we expand our validation capability. 
  • System Debugging: Investigate real failures on real equipment, using CAN traces, instrument logs, and bench tools to determine whether the fault lies in the test code, the fixture, or the unit under test. 
  • Continuous Integration: Add regression coverage to our CI pipelines so firmware changes are validated automatically rather than by hand. 
  • Documentation & Process: Contribute to documentation and test processes that support taking test systems from prototype toward production. 
  • You'll own a scoped project end to end and present your results to the engineering team at the close of the internship. 

Desired Qualifications: 

  • Background: Currently pursuing a BS or MS in Electrical Engineering, Computer Engineering, Computer Science, Mechatronics, or a related field. 
  •  Programming Foundations: Working proficiency in Python, including comfort reading and modifying a codebase you did not write. 
  • Testing Experience: Experience writing automated tests with pytest or a comparable framework, from coursework, projects, or prior internships. 
  • Version Control: Experience with Git and a pull-request-based development workflow. 
  • EE Fundamentals: Solid grasp of circuit basics - voltage, current, resistance, and power, and how they relate - sufficient to predict what a measurement should read and recognize when it doesn't. 
  • Hardware Fundamentals: Able to read a schematic, wiring diagram, or datasheet and act on it; hands-on experience working safely around energized equipment - power supplies, loads, or battery hardware - from lab work, projects, or prior internships. 
  • Communication Protocols: Familiarity with CAN, Modbus, SCPI, or other instrument and industrial protocols is a plus, even if only from classwork or personal projects. 
  • Linux: Familiarity with the Linux command line is a plus. 
  • Curiosity & Rigor: A safety-conscious mindset, strong attention to detail, and eagerness to learn how production test systems are built. Prior industry or energy storage experience is not expected.
