Auto-Generate Postman Collections from Traces

We’re excited to introduce a major upgrade to the BitDive ecosystem: native Postman support.

You can now generate a Postman Collection from your BitDive-generated JUnit replay tests with a single click. Postman export is an additional execution format alongside the BitDive runner, derived from the same runtime-grounded replay artifacts, so you can rerun and share endpoint requests without changing your regression suite.

BitDive automatically creates Unit and Component tests from recorded behavior, and it can now also export the tested application’s endpoint requests as Postman collections. This lets you invoke endpoints quickly, capture new executions back into BitDive, validate contracts against real scenarios, and compare “before” vs “after” behavior with diffs after a fix.

Why This Matters​

Automated regression suites are great at catching issues, but debugging is often manual.

When a test fails, developers usually want to rerun the exact request, inspect headers and payloads, and verify behavior quickly in a local, dev, or staging environment. Doing that by hand in Postman is slow and error prone, especially when requests include complex bodies, custom headers, or auth context.

With Export to Postman, BitDive removes the manual reconstruction step. You export the requests directly from the tests you already trust, import into Postman, and run them immediately.

How It Works​

The export is driven by your BitDive test definitions, not by raw trace data. BitDive reads the HTTP request configuration used by your generated JUnit replay tests and converts it into a Postman Collection.

You control how much you export.

Export Entire Scenarios​

Export a full scenario to get a single Postman collection that represents the full flow covered by your tests. This is ideal when you want to manually replay a complete user journey or share a reproducible workflow with someone else.

Export Specific Test Classes​

Need only a small slice of the suite? Export an individual test class to get a targeted collection for a specific component or service.

Exporting a specific test class to Postman

  1. Select Tests: Choose the tests, classes, or suites you want to run manually.
  2. Click Export: Hit "Export to Postman". BitDive builds a collection from your test configuration.
  3. Run in Postman: Import the generated JSON into Postman and click "Send".

Under the Hood​

The exporter generates a Postman Collection v2.1.0 compliant file and focuses on practical compatibility:

  • Test based generation: The collection is produced from BitDive’s generated JUnit replay tests (unit and component), so Postman mirrors what your regression suite executes.
  • Smart header processing: Request headers are normalized and formatted for Postman, so requests work out of the box.
  • Scenario structure: If a scenario or test includes multiple HTTP calls, they are exported as separate requests in the same collection in a predictable order.
  • Readable bodies: Request bodies are prettified for easier inspection, while keeping dynamic values intact.

Use Cases​

1. Manual debugging for failed regression tests​

When CI reports a failure, export the relevant scenario and rerun the same calls manually in Postman to inspect inputs and responses quickly.

2. Endpoint exploration without rebuilding requests​

Use Postman as a convenient UI to explore the exact requests your tests use, without copying payloads, rewriting headers, or reassembling auth.

3. Quick verification in Dev or Staging​

Run a small subset of calls against another environment to validate a hotfix before running the full regression suite.

4. A tight loop between manual runs and automated coverage​

If you manually trigger additional paths in Postman and BitDive captures them as new recordings, you can convert them into new replay tests to expand regression coverage over real behavior.

From real behavior to repeatable regression verification

BitDive turns captured executions into deterministic JUnit replay tests. Now you can also export those test calls to Postman for fast manual validation.
