hamcrest

I want to be able to make unit tests and instrumentation tests in Android Studio, and using Mockito in them. I'm using the new approach for tests in Android Studio 0.8. This is: building with gradle using official Android API for testing (ActivityInstrumentationTestCase2, etc) having the tests inside the directory of the app, not as a separate module launching the tests in Android Studio as a "Android Test" run configuration How can I write code in my tests that depends on libraries used only for the tests, such as mockito or hamcrest? I'd like to include these libraries when compiling and

This is my current test fragment: <packaging>eclipse-test-plugin</packaging> <dependencies> <dependency> <groupId>org.junit</groupId> <artifactId>com.springsource.org.junit</artifactId> <version>4.7.0</version> </dependency> </dependencies> with the following plugins configuration: <plugin> <groupId>org.eclipse.tycho</groupId> <artifactId>tycho-surefire-plugin</artifactId> <version>${tycho.version}</version> <configuration> <dependencies> <dependency> <type>p2-installable-unit</type> <artifactId>org.eclipse.equinox.ds</artifactId> </dependency> <dependency> <type>p2-installable-unit</type>

With Hamcrest we can easily test that exists at least one item in a list with a specific property, e.g. List<Pojo> myList = .... MatcherAssert.assertThat(myList, Matchers.hasItem(Matchers.<Pojo>hasProperty("fieldName", Matchers.equalTo("A funny string"))))); where the class Pojo is something like: public class Pojo{ private String fieldName; } That's nice, but how can I check that there is exactly one object in the list with the specificed properties? You might have to write your own matcher for this. (I prefer the fest assertions and Mockito, but used to use Hamcrest...) For example... import

import static org.junit.matchers.JUnitMatchers.both; import static org.junit.matchers.JUnitMatchers.containsString; Now I check it contains foo and bar as below ... Assert.assertThat(text, both(containsString("foo")). and(containsString("bar"))); What is cleanest way to test also check it contains 3 or more strings e.g. 'foo', 'bar' and 'baz' ? Use AllOf Assert.assertThat(test, CoreMatchers.allOf( containsString("foo"), containsString("bar"), containsString("bar2"), containsString("ba3"))); I don't know a elegant way in pure JUnit but you could take a look at Fixtures for Easy Software Testing

I want to write a unit test for my Kotlin code and use junit/hamcrest matchers, I want to use the is method, but it is a reserved word in Kotlin. How can I get the following to compile? class testExample{ @Test fun example(){ assertThat(1, is(equalTo(1)) } } Currently my IDE, InteliJ is highlighting that as a compilation error, saying it is expecting a ) after is ? In Kotlin, is is a reserved word . To get around this you need to escape the code using backticks, so the following will allow you to compile the code: class testExample{ @Test fun example(){ assertThat(1, `is`(equalTo(1)) } } David

I am quite confused. Currently I am testing my spring application using <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> I was happy as long as I wanted to match RegularExpressions. In hamcrest 1.3 you need to write your own matcher, which I did not like that much. I searched and found that hamcrest 2.0 has something build in, like: assertThat(DateHelper.getActualDateForXML(), MatchesPattern.matchesPattern("\\d{4}+-\\d{2}-+\\d{2}+T\\d{2}+:\\d{2}+:\\d{2}+")); I was happy, I added: <dependency> <groupId

I'm doing some tests with MockMvc, and I want to validate the structure of a JSON response. Specifically, I want to make sure that the key to an attribute exists, and that the value is of a certain type or null. { "keyToNull": null, # This may be null, or a String "keyToString": "some value" } The following works for me, but I'm wondering if there's a way to combine each group of two expectations into a single line, as I have a lot of attributes to check: import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*; import static org.hamcrest.Matchers.*; .andExpect
