Why testing infrastructure matters in Terraform - Quick Recap

Recall & Review

beginner

What is the main reason to test infrastructure code before deployment?

To catch errors early and avoid breaking live systems, ensuring reliability and stability.

intermediate

How does testing infrastructure code improve collaboration in teams?

It provides a shared understanding and confidence that changes won’t cause unexpected problems.

beginner

What can happen if infrastructure is deployed without proper testing?

It can cause downtime, security risks, and costly fixes due to misconfigurations or errors.

beginner

Name one common method to test infrastructure code in Terraform.

Using terraform plan to preview changes before applying them.

intermediate

Why is automated testing important for infrastructure as code?

It speeds up validation, reduces human error, and ensures consistent environments.

What does 'terraform plan' help you do?

A Delete all resources immediately

B Automatically fix errors in code

C Preview infrastructure changes before applying

D Deploy infrastructure without review

Terraform plan shows what changes will happen, helping catch mistakes before deployment.

Why is testing infrastructure code important?

A To slow down deployment

B To make code longer and more complex

C To ignore security risks

D To avoid downtime and errors in live systems

Testing helps prevent problems that could cause outages or security issues.

Which is NOT a benefit of infrastructure testing?

A Increased manual work

B Faster error detection

C Improved reliability

D Better team collaboration

Testing reduces manual errors and work by automating checks.

What risk does skipping infrastructure testing increase?

A Faster deployment

B Unexpected downtime

C Lower costs

D Better security

Skipping tests can cause outages due to unnoticed errors.

How does automated testing help infrastructure code?

A By running checks quickly and consistently

B By making manual reviews unnecessary

C By hiding errors from users

D By increasing deployment time

Automation speeds up testing and ensures consistent results.
