Selenium-Asserting the presence of multiple keywords of an array in a List

问题

Trying to check the presence of multiple keywords in a list.

List<String> array=new ArrayList<String>();
array.add("Sam Mayers test");
array.add("");
array.add("value");
array.add("");
array.add("");
array.add("");
array.add("District 49");
array.add("Till the last test");
array.add("Dawn Strings");
array.add("Lists value");
array.add("");
array.add("");
array.add("Total Hits Lists");
array.add("Values");


Boolean found = false;

        List<String> keywords_tobe_checked = new ArrayList<>();
        keywords_tobe_checked.add("Lists");
        keywords_tobe_checked.add("value");
        keywords_tobe_checked.add("Mayers");
        List<String> dummylist = new ArrayList<>();

        for (int i = 0; i < array.size(); i++) {
            String val = array.get(i);
            for (int j = 0; j < keywords_tobe_checked.size(); j++) {
            if (val.indexOf(keywords_tobe_checked.get(j)) >= 0) {
                dummylist.add(val);
            }
            }
        }
        System.out.println(dummylist);

        Assert.assertTrue(dummylist.containsAll(keywords_tobe_checked), "Its not correct");

My above code is failing on the asserttrue condition and giving me an incorrect result.

Is there a way i could pass this assertion by the condition that all the keywords mentioned in the "keywords_tobe_checked" are appearing in the "dummylist"?

Updated Code tried:

List<String> array=new ArrayList<String>();
        array.add("Sam Mayers test");
        array.add("");
        array.add("value");
        array.add("");
        array.add("");
        array.add("");
        array.add("District 49");
        array.add("Till the last test");
        array.add("Dawn Strings");
        array.add("Lists value");
        array.add("");
        array.add("");
        array.add("Total Hits Lists");
        array.add("Values");



        List<String> keywords_tobe_checked = new ArrayList<>();
        keywords_tobe_checked.add("Lists");
        keywords_tobe_checked.add("value");
        keywords_tobe_checked.add("Mayers");

        System.out.println(array);
        System.out.println(keywords_tobe_checked);
        for (String keyword : keywords_tobe_checked) {
            Boolean found = false;  
            for (String value : array) {
                if (value.contains(keyword)) {
                    found = true;
                    break;
                }
                Assert.assertTrue(found, "The keyword " + keyword + " not in the list");
            }

        }


 Content of the Array------------       [Sam Mayers test, , value, , , , District 49, Till the last test, Dawn Strings, Lists value, , , Total Hits Lists, Values]
  Content of the Keywords to be checked -----------------  [Lists, value, Mayers]
    Exception in thread "main" java.lang.AssertionError: The keyword Lists not in the list expected [true] but found [false]
        at org.testng.Assert.fail(Assert.java:94)
        at org.testng.Assert.failNotEquals(Assert.java:496)
        at org.testng.Assert.assertTrue(Assert.java:42)

When checking if List contains String the result will be true only when there is an exact match

array.contains("Lists"); // false

array.contains("Lists value"); // true

To check partial match you need to use the Assert.assertTrue inside the loop

for (String keyword : keywords_tobe_checked) {
    boolean hasKeyword = false;
    for (String value : array) {
        if (value.contains(keyword)) {
            hasKeyword = true;
            break;
        }
    }

    Assert.assertTrue(hasKeyword, "The keyword " + keyword + " is in the list");
}

What you are doing in your code is not correct due to values in Array List.

While using containsAll method you are looking for SPECIFIC String in Array List.

Example: The 1st list has object Sam Mayers test. The 2nd list has object Mayers.

This is why you have AssertionError. Sam Mayers test and Mayers are totally two different objects.
