JUnit Setup for my Android Studio Project<\/h1>\n

In the root directory of the project there is a filled called:<\/p>\n

build.gradle\r\n<\/pre>\n

The minor changes are as follows:
\nLine 26 goes with Line 110. I just added a variable for the junit version.\u00a0 I like how libGDX puts all of their versions in the same spot.\u00a0 It makes upgrading a lot easier.<\/h4>\n
The big changes are:
\nLine 110 makes the project depend on JUnit.
\nLine 112 makes the \/src\/test\/ folder called “test”<\/h4>\n
In Android Studio, I switched to the “project” view, and then created a new folder “test”<\/h4>\n
\"JUnit<\/h4>\n
\"setting-the-project-view-in-android-studio\"<\/p>\n
The “test” folder shows up green (see the arrow in the image below) in Android Studio when done correct – and you are in the “project” view.<\/p>\n
Under the “test” folder, I created a new package that matched my other package structure “com.stonemill.bubble”<\/p>\n
Lastly, in the package, I created a “BubbleTest” class with the contents as follows:<\/p>\n
BubbleTest.java<\/p>\n
package com.stonemill.bubble;\r\n\r\nimport org.junit.Assert;\r\nimport org.junit.Test;\r\n\r\npublic class BubbleTest{\r\n    @Test\r\n    public void testMove() throws Exception {\r\n        Assert.assertEquals(false, false);\r\n    }\r\n}\r\n<\/pre>\n
This is a stub class for the move method of the Bubble class.\u00a0 I can not add test methods as I code.<\/p>\n","protected":false},"excerpt":{"rendered":"
