You can insert the template into your file by writing the templates name, or by pressing ⌘+j to bring up the live template context menu, the you can search for the template by name.

Result block for service call

Use this within the completion block on a service call that takes a Result.

<template name="serresult" value="result -&gt;&#10;&#10;result.success?.let {&#10;&#10;}&#10;&#10;result.failure?.let {&#10;&#10;}" description="service results block" toReformat="true" toShortenFQNames="true">
  <context>
    <option name="KOTLIN_EXPRESSION" value="true" />
  </context>
</template>

Example output

result ->
  result.success?.let {
  }

  result.failure?.let {
  }

Mock var for unit test

<template name="mock" value="@Mock&#10;lateinit var $NAME$: $TYPE$" description="Mock var" toReformat="false" toShortenFQNames="true">
  <variable name="NAME" expression="" defaultValue="" alwaysStopAt="true" />
  <variable name="TYPE" expression="" defaultValue="" alwaysStopAt="true" />
  <context>
    <option name="KOTLIN_CLASS" value="true" />
  </context>
</template>

Example output

@Mock
lateinit var <name>: <type>

Where <name> and <type> are replaced on template insertion

Run with mock annotation

<template name="runwithmock" value="@RunWith(MockitoJUnitRunner::class)" description="Run With Mock annotation" toReformat="false" toShortenFQNames="true">
  <context>
    <option name="KOTLIN_TOPLEVEL" value="true" />
  </context>
</template>

Example

Adds @RunWith(MockitoJUnitRunner::class) to a class

Test function

<template name="testfun" value="@Test&#10;fun test_$NAME$() {&#10;    // Given&#10;    $END$&#10;    &#10;    // When&#10;    &#10;    &#10;    // Then&#10;    &#10;}&#10;" description="Test function" toReformat="true" toShortenFQNames="true">
  <variable name="NAME" expression="" defaultValue="" alwaysStopAt="true" />
  <context>
    <option name="KOTLIN_CLASS" value="true" />
  </context>
</template>

Example

@Test
fun test_<name>() {
  // Given
  <end>
  // When

  // Then
}

Where <name> is replaced on template insertion, and <end> is where the cursor will be placed once the name has been set (press enter after entering the name).
