# cargo-nextest

> A guide for generating Trunk-compatible test reports for Rust

You can automatically [detect and manage flaky tests](../../detection/) in your Rust projects by integrating with Trunk. This document explains how to configure cargo-nextest to output JUnit XML reports that can be uploaded to Trunk for analysis.

## Setup steps

Work through the steps below in order. Once you've finished the last one, you'll be ready to move on to [configure uploads in CI](../ci-providers/).

<Steps>
  <Step title={<a href="#generating-reports">Generate a compatible test report</a>} />

  <Step title={<a href="#report-file-path">Configure the report file path or glob</a>} />

  <Step title={<a href="#disable-retries">Disable retries for better detection accuracy</a>} />

  <Step title={<a href="#try-it-locally">Test uploads locally</a>} />
</Steps>

## Generating Reports

`cargo-nextest` has built-in reporting for JUnit XML reports, which is trunk-compatible. You can enable JUnit reporting by adding the following to your nextest config:

```toml title=".config/nextest.toml" theme={null}
[profile.ci.junit]
path = "junit.xml"
```

You can invoke this profile when running tests with:

```sh theme={null}
cargo nextest run --profile ci
```

### Report File Path

`cargo-nextest` outputs artifacts at `target/nextest` by default. When you provide a profile and a file name via the config example above, it produces a report at `target/nextest/ci/junit.xml`.

### Disable Retries

You need to disable automatic retries if you previously enabled them. Retries compromise the accurate detection of flaky tests.

Omit the `--retries` option.

## Try It Locally

### The Validate Command

You can validate your test reports using the [Trunk Analytics CLI](../../reference/cli-reference). If you don't have it installed already, you can install and run the `validate` command like this:

<CodeGroup>
  ```bash Linux (x64) theme={null}
  SKU="trunk-analytics-cli-x86_64-unknown-linux.tar.gz"
  curl -fL --retry 3 \
    "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
    | tar -xz

  chmod +x trunk-analytics-cli
  ./trunk-analytics-cli validate --junit-paths "./target/nextest/ci/junit.xml"
  ```

  ```bash Linux (arm64) theme={null}
  SKU="trunk-analytics-cli-aarch64-unknown-linux.tar.gz"
  curl -fL --retry 3 \
    "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
    | tar -xz

  chmod +x trunk-analytics-cli
  ./trunk-analytics-cli validate --junit-paths "./target/nextest/ci/junit.xml"
  ```

  ```bash macOS (arm64) theme={null}
  SKU="trunk-analytics-cli-aarch64-apple-darwin.tar.gz"
  curl -fL --retry 3 \
    "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
    | tar -xz

  chmod +x trunk-analytics-cli
  ./trunk-analytics-cli validate --junit-paths "./target/nextest/ci/junit.xml"
  ```

  ```bash macOS (x64) theme={null}
  SKU="trunk-analytics-cli-x86_64-apple-darwin.tar.gz"
  curl -fL --retry 3 \
    "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
    | tar -xz

  chmod +x trunk-analytics-cli
  ./trunk-analytics-cli validate --junit-paths "./target/nextest/ci/junit.xml"
  ```
</CodeGroup>

This will not upload anything to Trunk. To improve detection accuracy, you should address all errors and warnings before proceeding to the next steps.

### Test Upload

Before modifying your CI jobs to automatically upload test results to Trunk, try uploading a single test run manually.

You make an upload to Trunk using the following command:

```sh theme={null}
./trunk-analytics-cli upload --junit-paths "./target/nextest/ci/junit.xml" \
    --org-url-slug <TRUNK_ORG_URL_SLUG> \
    --token <TRUNK_ORG_TOKEN>
```

## Next Steps

Configure your CI to upload test runs to Trunk. Find the guides for your CI framework below:
