# Terraform Testing Quick Start
|
||||
|
||||
## Quick Commands
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
terraform test
|
||||
|
||||
# Run tests with verbose output
|
||||
terraform test -verbose
|
||||
|
||||
# Check formatting
|
||||
terraform fmt -check -recursive
|
||||
|
||||
# Auto-format all files
|
||||
terraform fmt -recursive
|
||||
|
||||
# Validate configuration
|
||||
terraform validate
|
||||
```
|
||||
|
||||
## Pre-Commit Checklist
|
||||
|
||||
Before committing changes, ensure:
|
||||
|
||||
- [ ] Code is formatted: `terraform fmt -recursive`
|
||||
- [ ] Configuration is valid: `terraform validate`
|
||||
- [ ] All tests pass: `terraform test`
|
||||
- [ ] No sensitive data is hardcoded
|
||||
|
||||
## Test File Locations
|
||||
|
||||
- `tests/resource_groups.tftest.hcl` - Default resource group tests
|
||||
- `tests/custom_configuration.tftest.hcl` - Custom configuration tests
|
||||
- `tests/variable_validation.tftest.hcl` - Variable validation tests
|
||||
|
||||
## Common Test Scenarios
|
||||
|
||||
### Adding a New Test
|
||||
|
||||
1. Choose the appropriate test file based on what you're testing
|
||||
2. Add a new `run` block with a descriptive name
|
||||
3. Use `command = plan` for most tests
|
||||
4. Add assertions with clear error messages
|
||||
5. Run the specific test to verify it works
|
||||
|
||||
Example:
|
||||
```hcl
|
||||
run "my_new_test" {
|
||||
command = plan
|
||||
|
||||
variables {
|
||||
resource_groups = {
|
||||
test = { name = "Test" }
|
||||
}
|
||||
}
|
||||
|
||||
assert {
|
||||
condition = <your_condition>
|
||||
error_message = "Clear description of what failed"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Testing a Specific Feature
|
||||
|
||||
```bash
|
||||
# Run specific test file
|
||||
terraform test -filter=tests/custom_configuration.tftest.hcl
|
||||
|
||||
# Run with verbose output for debugging
|
||||
terraform test -verbose -filter=tests/variable_validation.tftest.hcl
|
||||
```
|
||||
|
||||
## CI/CD Pipeline
|
||||
|
||||
Tests run automatically on:
|
||||
- Every push to master
|
||||
- Every pull request
|
||||
|
||||
Pipeline order:
|
||||
1. TFLint
|
||||
2. Tfsec
|
||||
3. Checkov
|
||||
4. **Terraform Test** ⬅ Your tests
|
||||
5. SonarQube
|
||||
6. Terraform Init/Plan/Apply
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Test Fails Locally But Not in CI
|
||||
|
||||
- Check Terraform version: `terraform version` (need >= 1.6.0)
|
||||
- Ensure environment variables are not interfering
|
||||
- Check for local `terraform.tfvars` overriding test values
|
||||
|
||||
### Test Fails in CI But Not Locally
|
||||
|
||||
- Review CI job output for environment-specific issues
|
||||
- Verify mock credentials are properly set in CI
|
||||
- Check for provider version mismatches
|
||||
|
||||
### Format Check Fails
|
||||
|
||||
```bash
|
||||
# Fix automatically
|
||||
terraform fmt -recursive
|
||||
|
||||
# Verify
|
||||
terraform fmt -check -recursive
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Write tests for new features**: Every new feature should have corresponding tests
|
||||
2. **Test edge cases**: Include tests for empty values, minimum/maximum values, etc.
|
||||
3. **Use descriptive names**: Test names should clearly indicate what they test
|
||||
4. **Clear error messages**: Help future developers understand failures quickly
|
||||
5. **Keep tests focused**: One test should verify one specific behavior

||||
- `terraform fmt` - Format configuration files
|
||||
- `terraform test` - Run test suites to validate module functionality
|
||||
- `terraform test -verbose` - Run tests with detailed output
|
||||
|
||||
### Development Workflow
|
||||
- Always run `terraform validate` and `terraform plan` before applying changes
|
||||
- Use `terraform.tfvars` file for environment-specific variable values
|
||||
- Secrets are managed through Vault - never hardcode sensitive values
|
||||
- Run `terraform test` to execute test suites before committing changes
|
||||
- Use `terraform fmt` to format code according to Terraform style conventions

# Terraform Testing Guide
|
||||
|
||||
This document describes the testing strategy and approach for the vSphere Resource Groups Terraform module.
|
||||
|
||||
## Overview
|
||||
|
||||
This module uses Terraform's native testing framework (introduced in Terraform 1.6.0) to ensure code quality and correctness. Tests are organized into multiple test files, each focusing on different aspects of the module's functionality.
|
||||
|
||||
## Test Structure
|
||||
|
||||
```
|
||||
tests/
|
||||
├── resource_groups.tftest.hcl # Tests for default resource group creation
|
||||
├── custom_configuration.tftest.hcl # Tests for custom configurations
|
||||
├── variable_validation.tftest.hcl # Tests for variable validation and edge cases
|
||||
└── setup/
|
||||
└── main.tf # Mock provider setup for testing
|
||||
```
|
||||
|
||||
## Test Coverage
|
||||
|
||||
### 1. Default Resource Groups (`resource_groups.tftest.hcl`)
|
||||
|
||||
Tests the default behavior when using the module without custom configuration:
|
||||
|
||||
- **Default Resource Groups Creation**: Verifies all 5 default resource groups (kubernetes, docker, infra, databases, app-servers) are created
|
||||
- **Shares Mapping Logic**: Validates the local shares_mapping values (low=500, normal=1000, high=2000)
|
||||
- **Tag Categories**: Ensures Environment and ResourceGroupType tag categories are properly configured
|
||||
- **Resource Group Tags**: Verifies tags are created for each resource group
|
||||
- **Default Configurations**: Validates default CPU/memory settings (expandable, no limits, no reservations)
|
||||
- **Output Validation**: Ensures all outputs are generated correctly
|
||||
- **Naming Conventions**: Verifies resource pools have correct display names
|
||||
|
||||
### 2. Custom Configuration (`custom_configuration.tftest.hcl`)
|
||||
|
||||
Tests advanced configuration scenarios:
|
||||
|
||||
- **High Priority Resources**: Custom CPU/memory reservations, limits, and high priority shares
|
||||
- **Low Priority Resources**: Validates low priority share allocation
|
||||
- **Non-Expandable Resources**: Tests fixed resource allocation (non-expandable)
|
||||
- **Multiple Custom Groups**: Validates creating multiple resource groups with different priorities
|
||||
- **Environment-Specific Configuration**: Tests environment variable integration
|
||||
- **Edge Cases**: Single resource group scenario
|
||||
|
||||
### 3. Variable Validation (`variable_validation.tftest.hcl`)
|
||||
|
||||
Tests input variable validation and edge cases:
|
||||
|
||||
- **Environment Values**: Validates accepted environment values
|
||||
- **Variable Types**: Ensures variables accept correct data types
|
||||
- **Resource Groups Structure**: Validates the resource_groups map structure
|
||||
- **Optional Parameters**: Verifies default values are applied correctly
|
||||
- **Shares Value Mapping**: Tests all three share levels (low, normal, high)
|
||||
- **Empty Configuration**: Handles empty resource_groups map
|
||||
- **Resource Limits**: Validates CPU/memory limits configuration
|
||||
|
||||
## Running Tests
|
||||
|
||||
### Locally
|
||||
|
||||
#### Run All Tests
|
||||
```bash
|
||||
terraform test
|
||||
```
|
||||
|
||||
#### Run Tests in Verbose Mode
|
||||
```bash
|
||||
terraform test -verbose
|
||||
```
|
||||
|
||||
#### Run Specific Test File
|
||||
```bash
|
||||
terraform test -filter=tests/resource_groups.tftest.hcl
|
||||
```
|
||||
|
||||
#### Run Specific Test Case
|
||||
```bash
|
||||
terraform test -filter=tests/resource_groups.tftest.hcl -verbose -test-directory=tests
|
||||
```
|
||||
|
||||
### In CI/CD Pipeline
|
||||
|
||||
Tests are automatically executed in the CI/CD pipeline as part of the `terraform-test` job:
|
||||
|
||||
1. **Format Check**: Validates Terraform formatting (`terraform fmt -check -recursive`)
|
||||
2. **Test Execution**: Runs all tests with verbose output
|
||||
3. **Test Report**: Generates and uploads test results as artifacts
|
||||
|
||||
The test job runs after security scanning (Checkov) and before SonarQube analysis.
|
||||
|
||||

|
||||
|
||||
## Writing New Tests
|
||||
|
||||
### Test File Structure
|
||||
|
||||
```hcl
|
||||
# Test description
|
||||
run "test_name" {
|
||||
command = plan # or apply
|
||||
|
||||
# Optional: Override variables
|
||||
variables {
|
||||
environment = "dev"
|
||||
resource_groups = {
|
||||
custom = {
|
||||
name = "Custom Group"
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
# Assertions
|
||||
assert {
|
||||
condition = <boolean_expression>
|
||||
error_message = "Descriptive error message"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Use Descriptive Test Names**: Test names should clearly describe what they're testing
|
||||
2. **One Concern Per Test**: Each test should focus on a single aspect or scenario
|
||||
3. **Clear Error Messages**: Error messages should explain what failed and why
|
||||
4. **Use Variables for Flexibility**: Override variables to test different scenarios
|
||||
5. **Test Edge Cases**: Include tests for empty inputs, minimum/maximum values, etc.
|
||||
6. **Use `plan` Command**: Most tests should use `command = plan` to avoid requiring actual infrastructure
|
||||
|
||||
### Example Test Pattern
|
||||
|
||||
```hcl
|
||||
run "validate_cpu_shares_mapping" {
|
||||
command = plan
|
||||
|
||||
variables {
|
||||
resource_groups = {
|
||||
test_group = {
|
||||
name = "Test"
|
||||
cpu_shares = "high"
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
assert {
|
||||
condition = vsphere_resource_pool.resource_groups["test_group"].cpu_shares == 2000
|
||||
error_message = "High CPU shares should map to 2000"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Test Requirements
|
||||
|
||||
- **Terraform Version**: >= 1.6.0 (required for native testing framework)
|
||||
- **Provider Version**: vsphere ~> 2.10
|
||||
- **Mock Data**: Tests use mock values for Vault credentials and vSphere resources
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Test Failures
|
||||
|
||||
1. **Review Test Output**: Use `-verbose` flag for detailed output
|
||||
2. **Check Assertions**: Verify the condition logic is correct
|
||||
3. **Validate Variables**: Ensure variable values match expected types
|
||||
4. **Review Changes**: If tests fail after code changes, review the modifications
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### Tests Skip Provider Validation
|
||||
Tests use mock credentials (`TF_VAR_role_id` and `TF_VAR_secret_id`) to avoid requiring actual infrastructure access during testing.
|
||||
|
||||
#### Format Check Failures
|
||||
Run `terraform fmt -recursive` to automatically format all Terraform files.
|
||||
|
||||
#### Test Hangs or Times Out
|
||||
This may indicate a provider authentication issue. Ensure mock credentials are properly set in the test environment.
|
||||
|
||||
## Test Metrics
|
||||
|
||||
Current test coverage includes:
|
||||
|
||||
- **Total Test Files**: 3
|
||||
- **Total Test Cases**: 20+
|
||||
- **Areas Covered**:
|
||||
- Resource creation and configuration
|
||||
- Tag management
|
||||
- Variable validation
|
||||
- Edge cases and error handling
|
||||
- Output generation
|
||||
|
||||
## Integration with Quality Gates
|
||||
|
||||
Tests are part of the overall quality assurance strategy:
|
||||
|
||||
1. **TFLint**: Code style and best practices
|
||||
2. **Tfsec**: Security scanning
|
||||
3. **Checkov**: Security and compliance checks
|
||||
4. **Terraform Test**: Functional correctness ⬅ New
|
||||
5. **SonarQube**: Code quality analysis
|
||||
6. **Terraform Plan**: Actual infrastructure validation
|
||||
|
||||
