A set of assert utilities for JUnit testing with Kotlin
Example
import org.junit.Test
import se.lovef.assert.v1.*
class ExampleTest {
@Test fun `example test`() {
1 shouldEqual 1
{ 1 shouldEqual 2 } throws Error::class
1 shouldBeLessThan 2 shouldBeLessThan 3
1 shouldBeCloseTo 1.1 tolerance 0.2
"my 1337 string" shouldContain "my" shouldContain 1337 shouldContain "string"
"my 1337 string" shouldNotContain "shit"
null.shouldBeNull()
("123" as String?).shouldNotBeNull().length shouldEqual 3
val exception = Exception()
; { throw exception } throws exception
{ { throw exception } throws Exception() } throws exception
{ { } throws exception } throws NotThrownError::class
{ "1 is 2" proof { 1 shouldEqual 2 } }
.throws(Error::class)
.message shouldEqual "1 is 2"
true.shouldBeTrue();
{ null.shouldBeTrue() } throws Error::class
listOf(1, "2", null).shouldNotBeEmpty() shouldContain "2" shouldNotContain -1
{ listOf(1, 2, 3) shouldEqual intArrayOf(1, 2, 3) }
.throws(Error::class)
.message shouldEqual """|
|Expected: <int[]> [1, 2, 3]
|Got: <ArrayList> [1, 2, 3]
""".trimMargin();
{ 1337 shouldEqual "1337" }
.throws(Error::class)
.message shouldEqual """|
|Expected: "1337"

""".trimMargin()
listOf(1, 3, 5) shouldAll { it % 2 shouldEqual 1 }
