Testing Source

The Testing source is used by local harnesses and CI to run a blueprint binary from the local filesystem instead of fetching artifacts from a registry or release.

Format

The Testing source has the following format:

pub struct TestingSource {
    pub cargo_package: String,
    pub cargo_bin: String,
    pub base_path: String,
}

Where:

• cargo_package - The Cargo package name of the binary (e.g., my-blueprint-bin)
• cargo_bin - The name of the built binary file (e.g., my-blueprint-bin)
• base_path - The base path of the binary crate (e.g., /home/user/my-blueprint/bin)

And they can be specified in the manifest of your binary crate like so:

[package.metadata.blueprint]
sources = [
    { type = "Testing", cargo_package = "some-package-name", cargo_bin = "some-binary", base_path = "/home/user/some-blueprint/bin" }
]

Output

After building your blueprint, you’ll notice something like the following in your blueprint.json:

{
  // ...
  "sources": [
    {
      "type": "Testing",
      "cargo_package": "my-blueprint-bin",
      "cargo_bin": "my-blueprint-bin",
      "base_path": "/home/user/my-blueprint/bin"
    }
  ],
}

It can safely be ignored (or deleted if you prefer).
