How to: Log data from your tests

Logging information is critical to the development and maintenance of your tests. AltWalker collects stdout and returned data from your tests.

Stdout

AltWalker captures stdout data from each test and outputs it to the stdout of altwalker cli, or to a file if --report-file option is used.

Python

class Simple:
    def vertex_a(self, *args):
        print("Simple.vertex_a")

[2020-04-27 14:26:20.731201] Simple.vertex_a Status: PASSED
Output:
Simple.vertex_a

C#/.NET

public class WalletModel
{
    public void vertex_a()
    {
        Trace.WriteLine("Simple.vertex_a");
    }
}

[2020-04-27 14:26:20.731201] Simple.vertex_a Status: PASSED
Output:
Simple.vertex_a

Custom Executor

Execute Step response:

{
    "payload": {
        "output": "Simple.vertex_a"
    }
}

[2020-04-27 14:26:20.731201] Simple.vertex_a Status: PASSED
Output:
Simple.vertex_a

Returned data from tests

AltWalker captures return value from each test and outputs it to the stdout of altwalker cli, or to a file if --report-file option is used.

Python

Return any json serializable object

class Simple:
    def vertex_a(self, *args):
        return { "key" : "value" }

[2020-04-27 14:26:20.731201] Simple.vertex_a Status: PASSED
Result:
{
    "key": "value"
}

C#/.NET

Return any json serializable object

public class WalletModel
{
    public object vertex_a()
    {
        return new Dictionary<string, string> () { {"key", "value" } };
    }
}

[2020-04-27 14:26:20.731201] Simple.vertex_a Status: PASSED
Result:
{
    "key": "value"
}

Custom Executor

Execute Step response:

{
    "payload": {
        "result": {"key" : "value"}
    }
}

[2020-04-27 14:26:20.731201] Simple.vertex_a Status: PASSED
Result:
{
    "key": "value"
}
