Test Runner API

Any way to run ava tests programatically i.e. From javascript file ?

[sindresorhus]

There's is an API, but it's not officially supported and might break at any time. const api = require('ava/api'). Example:

ava/test/api.js

Lines 34 to 40 in c1faf95

	const api = apiCreator();
	return api.run([path.join(__dirname, 'fixture/es2015.js')])
	.then(result => {
	t.is(result.passCount, 1);
	});
	});

See #1043 (comment).

Is there anything that I could do to help advance this? Or is this in more of the "need to think through the design / what we want" stage?

@davewasmer It's more that there are other parts of AVA's implementation that should be improved, and I personally don't want to also have to worry about how those changes impact a programmatic API. Lots of those issues are covered by the scope:scheduling label if you're interested.

I'd prefer to use ava from a programmatic entry point. Would love to see this made available 👍

I'm currently using this:

// main.ts
import * as child_process from "node:child_process";
import * as path from "node:path";
import * as process from "node:process";
import * as url from "node:url";
import * as glob from "glob";

const __dirname = path.dirname(url.fileURLToPath(import.meta.url));

void (async function () {
  const found = glob.sync("tests/**/*.test.ts", { cwd: __dirname });

  const NODE_OPTIONS = [
    "--experimental-strip-types",
    "--experimental-vm-modules",
    "--disable-warning=ExperimentalWarning",
  ]

  child_process.execFileSync(
    "node",
    [
      ...NODE_OPTIONS,
      path.join("node_modules", ".bin", "ava"),
      ...found,
    ],
    {
      cwd: __dirname,
      stdio: "inherit",
      env: {
        "NODE_OPTIONS": NODE_OPTIONS.join(" "),
        ...process.env,
      }
    }
  );
})();
