# Testing
The goal of the testing is to validate that the different nodes work together as intended. Kumologica tests will always assert against the response received by the flow given a collection of test cases.
A test case will be defined as an input message (test message) and a target node that will be the first node in handling that input message.
Kumologica Designer is of always-hot-deployment during local development, hence, there is no need to deploy before running the test cases.
# Defining a TestCase
Firstly, make sure that all your test flows are defined in the Test tab within Kumologica Designer.
A test flow is defined as one TestCase
node as an entry point, zero or more Assert
nodes, and ended with a TestCaseEnd
node. Following is an example of a test flow:

WARNING
If your TestCase
node does not appear in the dropdown of available test cases, make sure that the test flow is defined in the Test tab.
# Environment
All the environment parameters that are required to run the test can be defined in the test tab. Properties set in here will be available to the nodes within your flow under the object: env
Following is an example of two properties injected to the environment for testing:

# Assertions
Assertions is a basic element of testing. In Kumologica, an assertions is a node Assert
that you can chain together in order to validate any part of the response returned by a flow.
A test is marked as passed if all assertions are valid. The result of the assertions will be displayed on the assertions tab.
Following is an example of assertions result after a test execution:
