Introduction to automated testing

Tests guarantee quality, detect errors, facilitate maintenance, accelerate development with continuous integrations and secure deployments.

Types of tests

• We will focus on Unit tests
• Integration
• End to End

Unitary

• Unit tests have to be atomic
• It is recommended not to have dependencies on other components
• They must be specialized in the piece we are testing

Integration

• How do the elements work together?
• They should not be greater than the unitary ones

End to End
