In light of this, space technology and spacecrafts are increasingly complex and are using more software than ever before. For example, an advanced fighter aircraft relied on less than three million lines of code ten years ago. Today, the F-35 runs eight million lines of code. Space organisations have innovative ways of testing hardware and equipment ahead of launch, from pouring 450,000 gallons of water on rocket launchpad to capsule raft equipment for landing. However, it isn’t just the physical equipment that needs to be tested.
When it comes to testing technology that will be used in space travel, manually testing each piece of equipment will add a considerable amount of time to the preparation process. So, how is software tested quickly and efficiently?
To ensure that all aspects of the mission are vigorously tested, space organisations around the world are turning to automated testing. For example, for future space explorations—such as Orion—rigorous testing is taking place to ensure that onboard software and equipment works as expected and doesn’t suffer from any faults—even if subjected to strained use.
Space is a high-stakes environment, with large amounts of money—and possibly human lives—at risk if something goes wrong. Automated, vigorous testing ensures that the software and technology delivers the required outcomes both on land and in space.
AI-assisted and automated testing can provide predictive analytics for launch readiness, and can test many scenarios. This helps teams to predict quality issues that might occur, intelligently navigate applications, and identify and resolve issues quickly.
Testing software is important, but if it isn’t tested through the eyes of the astronauts who will be using the technology, it won’t be as effective. Using automated testing to test through the eyes of the user—alongside the full user experience, functionality, performance and usability—means that tests can ‘see’ and ‘do’ what the user can, and will test the user experience, not just the code.
For example, if something goes wrong while in space, the astronauts onboard will enter a stressful state, and might start using software more vigorously. Users might begin switching between screens rapidly, or rebooting programmes or software quickly. Because of this, the technology needs to be tested beforehand in ‘real-life scenarios’, to ensure that it is failure-proof in a variety of states, and can cope with how a real user would use the technology.
With automated testing, space organisations can test hundreds of scenarios quickly, and no longer need to spend time manually testing the software and technology. Automated testing can increase and scale alongside technology, learning and adapting to new processes and systems as the software becomes more intricate. AI and automation have the potential to hugely speed up technology advancements and safety in the business of outer space exploration so it’s an exciting time for industry. It’s also the ultimate test arena for testers.
