+```go
+ 
+// TestHappyMethod will test my new method
+func TestHappyMethod(t *testing.T) {
+    params := "my good input"
+    _, err := Client.V1().Method(params)
+	if err != nil {
+		t.Errorf("expected success running method: %v", err)
+		t.FailNow()
+	}
+}
+
+// TestSadMethod will false positive test my new method
+func TestHappyMethod(t *testing.T) {
+    params := "my bad input"
+    _, err := Client.V1().Method(params)
+    if err == nil {
+        t.Errorf("expected failure running method: %v", err)
