CWE: CWE-77 \u2014 Improper Neutralization of Special Elements used in a Command ('Command Injection')
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

Code:
func TestValidURL(t *testing.T) {
	testcases := []tcURLList{
		{"https://ssoTestURL.okta.com", true},
		{"https://ssoTestURL.okta.com:8080", true},
		{"https://ssoTestURL.okta.com/testpathvalue", true},
		{"-a calculator", false},
		{"This is a random test", false},
		{"file://TestForFile", false},
	}
	for _, test := range testcases {
		result := isValidURL(test.in)
		if test.out != result {
			t.Errorf("Failed to validate URL, input :%v, expected: %v, got: %v", test.in, test.out, result)
		}
	}
