Cucumber Java (Maven) - FileInputStream - java.lang.NullPointerException

Question

Hi people: I'm facing the next issue in Cucumber with Maven/Selenium/Java

Given I go to Google                                  # Step_First.I_go_to_Google()
      java.lang.NullPointerException
    at java.io.FileInputStream.<init>(FileInputStream.java:130)
    at java.io.FileInputStream.<init>(FileInputStream.java:93)
    at pages.Page_First.getURL(Page_First.java:38)
    at stepdefs.Step_First.I_go_to_Google(Step_First.java:22)
    at ✽.I go to Google (src/test/java/features/first.feature:8)

    When I query for "<search>" cucumber spring selenium        # Step_First.I_query_for_cucumber_spring_selenium(String)
    And click search                                            # Step_First.click_search()
    Then google page title should become the first page         # Step_First.google_page_title_should_become_the_first_page()

java.lang.NullPointerException
    at java.io.FileInputStream.<init>(FileInputStream.java:130)
    at java.io.FileInputStream.<init>(FileInputStream.java:93)
    at pages.Page_First.getURL(Page_First.java:38)
    at stepdefs.Step_First.I_go_to_Google(Step_First.java:22)
    at ✽.I go to Google (src/test/java/features/first.feature:8)

This is my feature file:

Feature: Navigation Test


  Scenario: Search google.com to verify google search is working

    Given I go to Google
    When I query for "<search>" cucumber spring selenium
    And click search
    Then google page title should become the first page

This is the Page method that I use:

public void getURL() throws IOException {

        Properties Config = new Properties();

        //Declares a variable for reading properties from a resource bundle file (*.properties)
        Properties p = new Properties();

        //Always the Absolute path here.
        FileInputStream file = new FileInputStream(System.getProperty("/Users/xxxxxx/Documents/automation_projects/" +
                "zero/src/main/resources/data/config.properties"));
        Config.load(file);

        driver.get(Config.getProperty("url"));

        //The String inside the config.properties
        String url = p.getProperty("url");
    }

In my step definition file I have this:

@Given("I go to Google")
    public void I_go_to_Google () throws IOException {

        page_first.getURL();
    }

Reviewing the information above, the issue occurs in this line:

FileInputStream file = new FileInputStream(System.getProperty("/Users/xxxxxx/Documents/automation_projects/" +
                "zero/src/main/resources/data/config.properties"));

By the way, my config.properties file:

browser = firefox
url = https://www.google.com

May anybody help me with this? Thanks in advance.

Yes, it is. I have modified the path to: src/main/resources/data/config.properties, but the results are the same. — nosequeweaponer, Feb 23 '20 at 15:21

Have you tried only using the file path without the call to System.getProperty ? I doubt you have a property with a key being a file name

I did it, but the result is the same. Actually it is reading the data from properties. The case is that is not recognizing it. – nosequeweaponer Feb 23 '20 at 15:25

When you use

        FileInputStream file = new FileInputStream(System.getProperty("/Users/xxxxxx/Documents/automation_projects/" +
            "zero/src/main/resources/data/config.properties"));

you try to look up a system property actually named /Users/xxxxx/..../config.properties which most likely doesn't exist, which therefore returns null which is then uncritically used as an argument to new FileInputStream(null) which then immediately fails.

Your understanding of how System.getProperty works is incorrect. Consider reading in a Properties file from that location and then work with that.

Then your code in the posting is not current. Please consider the time of others when asking here. – Thorbjørn Ravn Andersen Feb 24 '20 at 13:47
I don't know what you mean: If you see above "zero/src/main/resources/data/config.properties")); you can see that the information comes from the config.properties – nosequeweaponer Feb 24 '20 at 14:00
What do you think that `System.getProperty("/Users/xxxxxx/Documents/automation_projects/" + "zero/src/main/resources/data/config.properties")` does? – Thorbjørn Ravn Andersen Feb 24 '20 at 14:25
