Paw - Get last request made using specific environment

Question

I am trying to use a dynamic field from parsed response. The parsed response must be for the last request made using a specific environment. Is this possible?

Here's the scenario:

1. Make Request 1 using Environment A
    Receive Response A1
2. Make Request 1 using Environment B
    Receive Response B1
3. Make Request 2 using environment A, with field from parsed response A1
    Receive Response A2
4. Make Request 2 using environment B, with field from parsed response B1
    Receive Response B2

How do I orchestrate steps 3 and 4?

Answer 1

We are planning to implement it properly by using tabs on MacOS Sierra. With each tab operation as dedicated session and you will pin environment selection to a tab.

This is not properly implemented in Paw yet, but you can write a custom Dynamic value for this or use a hacky workaround:

1. Choose a partitioning variable in your environments

2. Set a X-paw-env header in Request 1 the partitioning environment variable. This way you get the current value of the partitioning variable depending on the environment

3. In Request 2 in the field where you are using the Response Parsed Body insert a Custom dynamic value instead. Inside there get the latest exchange for Request 1 where the request header matches the value of your partitioning variable for the current environment. Then extract the value you need from the response body using RegExp Match

function evaluate(context){
	var variableValue = 	context.getEnvironmentVariableByName("myPartitioningVariable").getCurrentValue()

	var exchanges = context.getRequestByName("Request1").getAllExchanges();
	for (var i = 0; i < exchanges.length; i++) {
		console.log(i, exchanges[i].requestHeaders["X-paw-env"]);
		if (variableValue === exchanges[i].requestHeaders["X-paw-env"]) {
			var dv = new DynamicValue("com.luckymarmot.RegExMatch", { re: '"user":\\s*"([^"]*)', input: exchanges[i].responseBody });
			console.log(exchanges[i].responseBody)
			console.log(i, "returning")
			return dv.getEvaluatedString();
		}
	}

};
