If you're diving into Salesforce Testing using Provar (which you totally should!), you've probably come across the term Named Credentials. Sounds fancy, right? But what exactly are they, and more importantly, how do you test them properly?
Well, you’re in the right place. In this blog, we’ll break down what Named Credentials are, why they’re important, and how to test them in a smooth and reliable way—especially when you're using a Salesforce-native test automation tool like Provar.
What Are Named Credentials in Salesforce?
Let’s simplify it. A Named Credential in Salesforce is basically a safe place where you store authentication details (like usernames, passwords, or tokens) so Salesforce can connect securely to an external system (like REST APIs). Think of it as a locker holding your access keys.
- Endpoint URL: The base URL of the external system.
- Authentication: Username-password, OAuth 2.0, AWS signature, etc.
- Named Credential Reference: Instead of hardcoding credentials, you reference this secure setup directly in your Apex or flow.
This way, you avoid hardcoding sensitive credentials and you get better security, logging, and governance.
Why Should You Test Named Credentials?
Great question. Because if something’s wrong with the connection or authentication, your integration won't work—simple as that. Here’s what can go wrong:
- Expired or incorrect credentials
- Changes in the external system's endpoint
- Incorrect permissions or scopes
In real-world automation scenarios, especially in a CI/CD pipeline, you want to make sure your Named Credentials are working as expected—before deploying to production. And that’s where Provar can really help.
How to Test Named Credentials Using Provar
Testing Named Credentials manually can be time-consuming and error-prone. But Provar simplifies this using its Salesforce-native integration and API testing capabilities. Let’s walk through how you can do it.
Step 1: Set Up Your Named Credential in Salesforce
- Navigate to Setup in Salesforce.
- Search for “Named Credentials”.
- Click “New Named Credential”.
- Fill out the endpoint URL, authentication method, and save.
Make sure to test it using the “Test Connection” button inside Salesforce. If it fails here, don’t even bother testing it in automation yet—it needs to be fixed first.
Step 2: Create an API Test in Provar
Here’s where Provar steps in like a pro.
- Open Provar Desktop.
- Go to “Test Cases” and click “New API Test Case”.
- Select the request type (GET, POST, etc.) and the endpoint.
- Instead of hardcoding credentials, use the Named Credential by referencing it as part of your Salesforce environment configuration or within headers.
Provar automatically pulls in the authentication mechanism from your Salesforce environment (thanks to metadata!) so you don’t have to reconfigure it manually.
Step 3: Validate the Response
Once the request is sent, use Provar’s assertion features to check:
- HTTP status codes (200, 401, etc.)
- Response body (Is the data what you expected?)
- Error messages (Helpful if something goes wrong)
You can even parameterize the test and use Test Data Services to loop through different scenarios and tokens.
Common Mistakes to Avoid
We’ve worked with a lot of teams and seen some avoidable missteps. Here are a few tips:
| Mistake | What to Do Instead |
|---|---|
| Hardcoding credentials in the test | Always use Named Credentials or secure vault references in Provar |
| Not checking token expiry | Set up assertions to test for token validity |
| Not testing failure scenarios | Simulate expired or invalid tokens in your test cases |
Can You Automate This? Absolutely.
With Provar, you can integrate this as part of your regular CI/CD pipeline. You can:
- Run these tests during deployment
- Automatically validate integrations using Named Credentials
- Send results to your Provar Manager dashboard for reporting
This is why Provar is the go-to for Salesforce teams looking to scale Salesforce Testing with confidence.
Best Practices When Testing Named Credentials
Here are a few expert-level tips:
- Use separate Named Credentials for sandbox and production.
- Apply strict access policies and monitor usage logs.
- Always test both valid and invalid states (e.g., expired tokens).
- Include timeout and retry scenarios in your tests.
Want bonus points? Create a Provar test that runs daily to validate the health of all your active Named Credentials. If one fails, have it email your team or create a Jira ticket automatically.
