Consul Testing Utilities ======================== This package provides some generic helpers to facilitate testing in Consul. TestServer ========== TestServer is a harness for managing Consul agents and initializing them with test data. Using it, you can form test clusters, create services, add health checks, manipulate the K/V store, etc. This test harness is completely decoupled from Consul's core and API client, meaning it can be easily imported and used in external unit tests for various applications. It works by invoking the Consul CLI, which means it is a requirement to have Consul installed in the `$PATH`. Following is an example usage: ```go package my_program import ( "testing" "github.com/hashicorp/consul/consul/structs" "github.com/hashicorp/consul/testutil" ) func TestMain(t *testing.T) { // Create a server srv1 := testutil.NewTestServer(t) defer srv1.Stop() // Create a secondary server, passing in configuration // to avoid bootstrapping as we are forming a cluster. srv2 := testutil.NewTestServerConfig(t, func(c *testutil.TestServerConfig) { c.Bootstrap = false }) defer srv2.Stop() // Join the servers together srv1.JoinLAN(srv2.LANAddr) // Create a test key/value pair srv1.SetKV("foo", []byte("bar")) // Create lots of test key/value pairs srv1.PopulateKV(map[string][]byte{ "bar": []byte("123"), "baz": []byte("456"), }) // Create a service srv1.AddService("redis", structs.HealthPassing, []string{"master"}) // Create a service check srv1.AddCheck("service:redis", "redis", structs.HealthPassing) // Create a node check srv1.AddCheck("mem", "", structs.HealthCritical) // The HTTPAddr field contains the address of the Consul // API on the new test server instance. println(srv1.HTTPAddr) } ```
