How to add Basic Authentication while creating Jmeter Script from Jmeter API using java?

Question

I have gone through some of the scripts, where we can create Jmeter scripts from scratch using apache jmeter api.

But, not able to add authorization to my api testing scripts.

I know 'AuthManager' class is available for it, But, I am not able to use it correctly, I am geeting unauthorised error, even if i give correct credentials.

Please help me out!

You need to add an instance of AuthManager to your Test Plan The relevant code would be something like:

AuthManager manager = new AuthManager();
Authorization authorization = new Authorization();
authorization.setURL("http://example.com");
authorization.setUser("foo");
authorization.setPass("bar");
manager.addAuth(authorization);
manager.setName(JMeterUtils.getResString("auth_manager_title")); // $NON-NLS-1$
manager.setProperty(TestElement.TEST_CLASS, AuthManager.class.getName());
manager.setProperty(TestElement.GUI_CLASS, AuthPanel.class.getName());

Full test plan just in case:
