What is regression testing? Perform testing of existing software functionality to detect the impact of code changes on existing functionality. Types of regression testing strategies: Risk-based strategy Coverage-based strategy Timeline-based strategy Hybrid strategy (combine the above strategies) Regression testing in action in Golang: Implementing a regression testing strategy using a list of test cases and the output of a unit test function test function: Identify high-risk areas Create test cases targeting these areas Automatically run tests Set code coverage thresholds
Regression testing strategy in Golang function testing
Regression testing is an essential type of testing in software development, which ensures that existing functionality still works properly after code changes. When writing tests for Go functions, a regression testing strategy is crucial to prevent the introduction of new bugs.
What is regression testing?
Regression testing is a set of tests that are repeatedly run against existing functions in the software. Its purpose is to detect the impact of code changes on existing functionality, such as fixing bugs, adding new features, or refactoring code.
Types of regression testing strategies
The following are common regression testing strategies:
Regression testing practice in Golang
We use Go language to create a simple function to demonstrate regression testing:
package main import ( "testing" ) func Sum(a, b int) int { return a + b } func TestSum(t *testing.T) { tests := []struct { a, b, expected int }{ {1, 2, 3}, {3, 4, 7}, {-1, -2, -3}, } for _, test := range tests { actual := Sum(test.a, test.b) if actual != test.expected { t.Errorf("Sum(%d, %d) = %d, expected %d", test.a, test.b, actual, test.expected) } } }
We create A unit test function TestSum
, which contains a list of test cases. Each test case contains input values and expected results. During testing, we iterate through the test cases and test whether the output of the Sum
function matches the expected result.
Implementing a regression testing strategy
In order to implement a regression testing strategy, we need to:
By following these steps, we can build a robust regression testing strategy to ensure that Go functions still work properly after changes are made.
