Selenium Web驱动程序-Java-TestNG-Assert.assertEquals如何将实际结果与预期结果之间的范围进行比较

Question

I have test scenario where actual result is fix percentage For example 135.68% but I want to compare actual result with the Expected result which is in range For example 130.00 to 136.00. If actual result fall between the range of 130.00 to 136.00 then test is pass otherwise test is fail.

I am using following Assert statement but no luck:

  import java.awt.Robot;
    import java.awt.event.KeyEvent;
    import java.io.File;
    import java.io.FileInputStream;
    import java.text.DateFormat;
    import java.text.SimpleDateFormat;
    import java.util.Date;
    import jxl.Sheet;
    import jxl.Workbook;
    import org.apache.commons.io.FileUtils;
    import org.openqa.selenium.By;
    import org.openqa.selenium.OutputType;
    import org.openqa.selenium.TakesScreenshot;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.support.ui.Select;
    import org.testng.Assert;
    import org.testng.annotations.Test;
    import org.testng.asserts.Assertion;
    import org.testng.asserts.SoftAssert;


    @Test
    public class TC20042 extends BaseClass{

        private SoftAssert m_assert = new SoftAssert();


          public void registration() throws Exception, InterruptedException {
                  FileInputStream fi=new FileInputStream("C:\\File\\Book2.xls");
                  Workbook w=Workbook.getWorkbook(fi);
                  Sheet s=w.getSheet(2);


                try
                {
                for (int i = 0; i < s.getRows(); i++)
                {
                //Read data from excel sheet
                    String s1 = s.getCell(0,i).getContents();

    String xPath = "//*[@id='mainForm']/div/div[3]/div/div/table/tbody/tr[1]/td[6]";
                    String text = driver.findElement(By.xpath(xPath)).getText();
                    double percentage = Double.parseDouble(text);

                    assertThat(percentage).isBetween(130.0, 136.0);

private Object assertThat(double percentage) {
            // TODO Auto-generated method stub
            return null;
        }   



    }

                }
                catch(Exception e)
                {
                System.out.println(e);

                }
                }

    }

Answer 1

Simply parse and check:

    String expectedPercentage = driver.findElement(By.xpath("//*[@id='app-banner']/div[1]/div/h2")).getText().replace("%", "");
    double percentage = Double.parseDouble(expectedPercentage);

    // Do this parsing if range is in string format. Otherwise skip this block
    String range = "130.00 to 136.00";
    String[] numbers = range.replaceAll(" ", "").split("to");        
    double min = Double.parseDouble(numbers[0]);
    double max = Double.parseDouble(numbers[1]);

    Assert.assertTrue(expectedPercentage + " is not between the range", min <= percentage && percentage <= max);

Answer 2

Parse the text and assert the result:

String xPath = "//*[@id='app-banner']/div[1]/div/h2";
String text = driver.findElement(By.xpath(xPath)).getText();
double percentage = Double.parseDouble(text.replace("%", ""));

assertThat(percentage).isBetween(130.0, 136.0);

This solution uses isBetween(Double, Double) from AssertJ as a static import . Alternatively, you can use the TestNG assertion I mentioned in my comment .

Answer 3

public static void assertEquals(double actual,
                                double expected,
                                double delta,
                                java.lang.String message)
Asserts that two floats are equal concerning a delta. If they are not, an AssertionError, with the given message, is thrown. If the expected value is infinity then the delta value is ignored.

assertEquals(133.00,expected,3.00,"ERROR")

Answer 4

I used regular testNg Assert and it worked for me as below:

String xPath = "//*[@id='mainForm']/div/div[3]/div/div/table/tbody/tr[1]/td[6]";
                String text = driver.findElement(By.xpath(xPath)).getText();
                text  = text.replace("%", "");
                double percentage = Double.parseDouble(text);   

                Assert.assertTrue(percentage > 130.67 && percentage < 135.69);
