Is this suited for github?

  • Yes, this is suited for github

implementing a new adapter I can sucesfully past tests having

count: async ({
          model,
          where,
        }: {
          model: string;
          where?: Required<Where>[];
        }): Promise<number> => {
          console.log("count model:", model);
          console.log("count where:", where);
          // ...

          return -1;
        },

It looks like you’re working on a new adapter and want to verify that the count implementation is tested correctly. I recommend creating a test file alongside your adapter source file. In that test, you can call the count function with dummy parameters, verify that the adapter logs the correct model and where conditions, and check that the returned value (currently –1) meets your expectations. For example, you can set up assertions to verify that the count is handled as intended and then later modify the count logic based on your requirements [1].

Are you planning to integrate this adapter test into your CI pipeline, or would you like any further guidance on structuring your tests? Tag @better-auth-agent if you would like an answer from the Agent.

I am manually running

 npx vitest run ./better-auth-jwt-adapter.test.ts --bail 1

where the file contains, as per your doc

import { describe, afterAll } from "vitest";
import { runAdapterTest } from "better-auth/adapters/test";
import { BetterAuthJwtAdapter } from "./better-auth-jwt-adapter";

describe("My Adapter Tests", async () => {
  afterAll(async () => {
    // Run DB cleanup here...
  });
  const adapter = BetterAuthJwtAdapter({
    debugLogs: {
      // If your adapter config allows passing in debug logs, then pass this here.
      isRunningAdapterTests: true, // This is our super secret flag to let us know to only log debug logs if a test fails.
    },
  });
  await runAdapterTest({
    getAdapter: async (betterAuthOptions = {}) => {
      return adapter(betterAuthOptions);
    },
  });
});

@better-auth-agent all test passed even if my count function is not implemented

 Test Files  1 passed (1)
      Tests  25 passed | 2 skipped (27)
   Start at  16:38:23
   Duration  206ms (transform 39ms, setup 0ms, collect 94ms, tests 20ms, environment 0ms, prepare 2ms)

This is due the fact, dear my @better-auth-agent , that no test is currently implemented for the count method of an adapter

Hi there! It looks like your tests are passing because there isn’t any test asserting the behavior of the count function. Essentially, since no test is checking for count’s output, even a stubbed implementation that simply returns –1 will pass. To move forward, you have a couple of options:

• Add a custom test case for the count method that verifies its expected behavior (for example, returning the correct number based on provided filters). This way, any future changes to count will be caught.

• If count isn’t needed for your use case, consider removing it from your adapter’s interface and update your test suite accordingly.

Which approach would work best for your adapter’s design? Tag @better-auth-agent if you would like an answer from the Agent.

Hello there! To ensure your new adapter’s count method is well covered, you can add a dedicated test case that does the following:

• Call the count method with specific model names and filter objects as input.
• Verify that the console logs the expected parameters (model and where).
• Assert that the returned value matches the expected output (e.g., –1, if that is what you intend as a placeholder).

Following our testing best practices, remember to place the test file alongside its source file and include clear commit messages when you add your test case [1]. Have you set up your testing environment with vitest? Tag @bekacru and @ping__ if you’d like further assistance, and tag @better-auth-agent if you would like an answer from the Agent. What additional tests or behaviors would you like to verify for your adapter?

Thanks for reaching out! To address this issue, please ensure that your adapter’s count method is properly integrated into your test suite. Here are some next steps:

• Confirm that your test file is placed next to your source file (following our best practices for test file structure) so that it picks up the adapter implementation automatically [1].

• In your test, invoke the count method with a sample model and where clause to validate that it logs the expected values (“count model:” and “count where:”) and returns the correct count. For troubleshooting, if the adapter returns –1 (as in your current implementation), verify that this is the intended behavior or adjust the code accordingly.

• Since your issue requests to “add label ‘test’”, we’ve added the label for you.

Does this clarify the next steps for you? Feel free to tag @bekacru or @ping__ if you need further input, and tag @better-auth-agent if you would like an answer from the Agent. What additional questions can we help with regarding your adapter implementation?

Hey, thanks for reporting this!

I checked and found that normalTestSuite (in packages/better-auth/src/adapters/tests/normal.ts) already has tests that validate count returns the correct number:

  • "count - should count many models" (line 1374)
  • "count - should return 0 with no rows to count" (line 1389)
  • "count - should count with where clause" (line 1401)

These should fail if count returns -1.

Could you share:

  1. Which test suite you're running?
  2. Your adapter's test setup code?

This will help me understand if:

  • There's a gap in test coverage I need to fix, OR
  • You need to include normalTestSuite in your adapter tests

Yeah , That's our old, deprecated test runner.
The normalTestSuite is the one that has the proper count tests . As soon as you switch to this new testAdapter setup, your adapter's -1 return value will fail the test exactly as you expected.
