Lambda handlers with support for callbacks use the typical Node.js asynchronous signature:
exports.handler = function( event, context, callback ) {
callback( null, 'success!' );
}
The following example shows a simple case for validating that the Lambda (handler) was called successfully (i.e. callback( null, result )
:
const LambdaTester = require( 'lambda-tester' );
const myHandler = require( '../index' ).handler;
describe( 'handler', function() {
it( 'test success', function() {
return LambdaTester( myHandler )
.event( { name: 'Fred' } )
.expectResult();
});
});
If the handler decides to call callback( err )
then the verification will fail and the test will fail.
Additionally, if one wanted to test for failure, then the following code would be used:
const LambdaTester = require( 'lambda-tester' );
const myHandler = require( '../index' ).handler;
describe( 'handler', function() {
it( 'test failure', function() {
return LambdaTester( myHandler )
.event( { name: 'Unknown' } )
.expectError();
});
});
Please note that you must return the LambdaTester
back to the framework since lambda-tester
is asynchronous and uses Promises.
