Integration testing in Terraform means deploying real infrastructure and running tests to check if components work together correctly.
Execution Sample
Terraform
terraform init
terraform apply -auto-approve
run integration tests
terraform destroy -auto-approve
This sequence deploys infrastructure, runs tests to check integration, then cleans up resources.

Key Moments - 3 Insights
Why do we need to deploy real infrastructure for integration testing?
Because integration tests check if different parts work together in a real environment, not just in code. See execution_table step 2 and 3.
What happens if tests fail after deployment?
You fix the Terraform code and rerun deployment and tests until they pass, as shown in execution_table steps 4 and 6.
Why destroy infrastructure after tests?
To avoid extra costs and keep the environment clean. This is step 7 in the execution_table.
Visual Quiz - 3 Questions
Test your understanding
Look at the execution_table, what is the result after running 'terraform apply -auto-approve'?
ATerraform ready to deploy
BResources created in cloud
CResources removed
DTests pass or fail
💡 Hint
Check Step 2 in the execution_table under Result column.
At which step do integration tests run according to the execution_table?
AStep 3
BStep 1
CStep 5
DStep 7
💡 Hint
Look at Step 3 in the execution_table under Action column.
If tests fail, what is the next action based on the execution flow?
ADestroy infrastructure immediately
BConfirm infrastructure works
CFix code and retry deployment
DSkip tests and proceed
💡 Hint
See the branch after 'Check test results' in concept_flow and Step 6 in execution_table.
Concept Snapshot
Integration testing with Terraform:
1. Write Terraform code
2. Deploy real infrastructure (terraform apply)
3. Run tests to check resource interaction
4. Fix code if tests fail
5. Destroy infrastructure after tests
Key: Test real deployed resources, not just code.
Full Transcript
Integration testing strategies in Terraform involve deploying actual cloud resources using 'terraform apply', then running tests to verify that these resources work together correctly. If tests pass, the infrastructure is confirmed; if not, the Terraform code is fixed and redeployed. After testing, resources are destroyed to avoid costs. This cycle repeats until tests pass, ensuring reliable infrastructure integration.
