Comparing array element using Junit

Question

I have a two string array in java where I am comparing the whole array using assertArrayEquals. example:

Expected:[CTSCAT, CTSSCH, PERSONS, ID, CTSCAT, CTSSCH, ORDERS, PERSONID, 1, 3, 3, FK_PERSONORDER, PK_PERSON, 7]

Actual:[CTSCAT, CTSSCH, PERSONS, ID, CTSCAT, CTSSCH, ORDERS, PERSONID, 1, 3, 3, FK_PERSONORDER, PK_PERSON, 7]

But know I want to compare some element of array instead of entire array. Like in same example I only want to check first two element.

You can compare with the help of assertEquals:

assertEquals(arr1[0],arr2[0]);

and so on..

I thought of writing a function where it can use assertEqual for the indexes but i thought their might be some other way for this.

You can try with assertThat clause too...You can convert your arrays into list and then try: assertThat(list1, contains(list2.get(0),list2.get(1)); You can apply combinations further to that

Try using AssertJ library. It has very good support for arrays and its much more readable.

You can find the array example here

You can use Hamcrest matchers (javadoc):

assertThat(arr1, Matchers.arrayContaining(arr2));
