## Description Presently, any tests using our old configs happen in place. This is problematic, as it changes the files themselves. This means that anyone running the tests will cause unintentional modifications, which stand a chance of being committed and merged into main. We want these old database files to remain untouched, thus we copy them to a temp directory prior to running our tests. ## Meta Merge checklist: - [x] Pull Request title is [short, imperative summary](https://cbea.ms/git-commit/) of proposed changes - [x] The description documents the _what_ and _why_, including events that led to this PR - [ ] If this PR changes behavior or adds a feature, user documentation is updated - [ ] If this PR touches photon-serde, all messages have been regenerated and hashes have not changed unexpectedly - [ ] If this PR touches configuration, this is backwards compatible with all settings going back to the previous seasons's last release (seasons end after champs ends) - [ ] If this PR touches pipeline settings or anything related to data exchange, the frontend typing is updated - [ ] If this PR addresses a bug, a regression test for it is added
PhotonVision
PhotonVision is the free, fast, and easy-to-use computer vision solution for the FIRST Robotics Competition. You can read an overview of our features on our website. You can find our comprehensive documentation here.
The latest release of platform-specific jars and images is found here.
If you are interested in contributing code or documentation to the project, please read our getting started page for contributors and join the Discord to introduce yourself! We hope to provide a welcoming community to anyone who is interested in helping.

Authors
Building
Gradle is used for all C++ and Java code, and pnpm is used for the web UI. Instructions to compile PhotonVision yourself can be found in our docs.
You can run one of the many built in examples straight from the command line, too! They contain a fully featured robot project, and some include simulation support. The projects can be found inside the photonlib-java-examples and photonlib-cpp-examples subdirectories, respectively. Instructions for running these examples directly from the repo are found in the docs.
Gradle Arguments
Note that these are case sensitive!
-PArchOverride=foobar: builds for a target system other than your current architecture. Valid overrides are:- winx64
- winarm64
- macx64
- macarm64
- linuxx64
- linuxarm64
- linuxathena
-PtgtIP: Specifies where./gradlew deployshould try to copy the fat JAR to-PtgtUser: Specifies custom username for./gradlew deployto SSH into-PtgtPw: Specifies custom password for./gradlew deployto SSH into-Pprofile: enables JVM profiling-PwithSanitizers: On Linux, enables-fsanitize=address,undefined,leak
If you're cross-compiling, you'll need the WPILib toolchain installed. This must be done via Gradle: for example ./gradlew installArm64Toolchain or ./gradlew installRoboRioToolchain
