"No tests found. Nothing was run" message in console , unable to understand why - selenium

Question

Below is the code am trying to execute
Not sure why am getting [TestNG] No tests found. Nothing was run
if I remove the before class annotation method, it executes but fails due the dependency
public class TestNG_Practice3 {
static WebDriver driver ;
String url = "https://in.linkedin.com/";
#BeforeClass(description = "To open the browser")
public void openBrowser()
{ driver = new FirefoxDriver();
driver.get(url);
System.out.println("Browser got open");
}
#Test (dependsOnMethods ="openBrowser",description = "To signin")
public void login()
{
driver.manage().timeouts().implicitlyWait(2000, TimeUnit.SECONDS);
WebElement signin = driver.findElement(By.id("login-email"));
Assert.assertTrue(signin.isDisplayed());
WebElement password = driver.findElement(By.id("login-password"));
WebElement signinbutton = driver.findElement(By.id("login-submit"));
signin.sendKeys("xyz");
password.sendKeys("abc");
signinbutton.click();
Assert.assertTrue(driver.getCurrentUrl().contains("feed/"));
}
#Test(dependsOnMethods = "login")
public void logout()
{
WebElement meDropdown = driver.findElement(By.xpath("//*[#id=\"nav-settings__dropdown-trigger\"]/div/span[2]/li-icon/svg"));
meDropdown.click();
WebElement logout = driver.findElement(By.id("ember545"));
logout.click();
}
#AfterClass
public void closebrowser()
{
driver.quit();
}
}

Answer 1

Step-1 : Basic trial with Project Build,
public class TestNG_Demo {
#BeforeClass
public void openbrowser()
{
System.out.println("Browser got open");
}
#Test
public void testbrowser()
{
System.out.println("Test execution");
}
#AfterClass
public void closebrowser()
{
System.out.println("Browser got close");
}
}
So you will be have idea, Your project build get successful execution.
If you have maven project and Build did not get pass, you will be have trigger what is causing from maven build dependency.
Update
Step-2 : After tracing first trial
public class TestNG_Demo {
#Test
public void testbrowser()
{
WebDriver driver = new FirefoxDriver();
driver.get("http://google.com");
}
}

Answer 2

Remove dependsOnMethods ="openBrowser" because it's not a test method and will be execute before test without it
