📋 Detailed Test Examples

Functional Test Example

def "should handle complex OR operations with mixed field types"() {
    given: "GraphQL query with complex OR conditions"
    def query = '''
        query {
            customer(or: [
                { customer_id: { lt: 5 } },
                { first_name: { startsWith: "A" } },
                { active: { eq: true } }
            ]) {
                customer_id
                first_name
                active
            }
        }
    '''
    
    when: "executing the query"
    def result = graphqlTester.query(query).execute()
    
    then: "should return filtered results"
    result.errors.isEmpty()
    result.data.customer.size() >= 3
}

Performance Test Example

def "should handle large IN arrays efficiently"() {
    given: "large array of 1000 customer IDs"
    def largeIdArray = (1..1000).collect { it }
    
    when: "filtering with large IN array"
    def startTime = System.currentTimeMillis()
    def result = performQuery(largeIdArray)
    def endTime = System.currentTimeMillis()
    
    then: "should complete within performance threshold"
    endTime - startTime < 600 // 600ms threshold
    result.data.customer.size() > 0
}

Security Test Example

def "should prevent SQL injection in string filters"() {
    given: "malicious SQL injection payload"
    def maliciousInput = "'; DROP TABLE users; --"
    
    when: "attempting SQL injection"
    def result = graphqlTester.query("""
        query {
            users(where: { name: { eq: "$maliciousInput" } }) {
                id name
            }
        }
    """).execute()
    
    then: "should safely handle malicious input"
    result.errors.isEmpty()
    result.data.users.size() == 0
    // Database should remain intact
}

🎯 Test Maintenance

Adding New Tests

  1. Follow naming conventions: Use descriptive test method names
  2. Test both positive and negative cases
  3. Include performance assertions where appropriate
  4. Add security validation for new filter types
  5. Document edge cases and expected behaviors

Test Data Management

// Standard test data setup
def setupData() {
    // Create varied test records
    customerRepository.saveAll([
        new Customer(name: "Alice", active: true, created: "2023-01-01"),
        new Customer(name: "Bob", active: false, created: "2023-06-15"),
        // ... more test data
    ])
}
