This project is a global extension for Spock to create test (or, in Spock terms, Specifications) reports.
By default, the report creator generates a HTML report for each Specification, as well as a summary of all Specifications that have been run (index.html).
If you prefer to have your own template to generate reports from, you can use the TemplateReportCreator. This allows you to generate reports in any text format. See the "Using template reports" section below.
Support for Geb tests: if you use Geb for web testing, check out the geb-spock-reports extension which adds screenshots to Spock reports.
I am using CodePen to design the HTML feature report, which contains detailed information about each Specification run by Spock, including the examples given (Where block) and their results, if any, and the summary report, which summarizes the results of all Specification runs. Click on the links to see the reports used for testing.
If you don't like the styles, you can use your own css stylesheets (see the customization section below). I welcome feedback on how to improve the report looks!
To enable this Spock extension, you only need to declare a dependency to it (if using Maven, Ivy, Gradle etc) or, just add the jar to the project's classpath.
Spock-reports is available on Maven Central.

}If you prefer, you can just download the jar directly from Maven Central.
The only dependencies this project has are Groovy (only the
groovy, groovy-templates, groovy-xml and groovy-json modules are required)
and Spock, of course.
If you want to add information to your Spock-reports programmatically, since version 1.4.0, you can use the following
Specification class' extension methods which are added by Spock Reports:
void reportHeader( arg )- dynamically insert data into the top of the Specification report.void reportInfo( arg )- add data to the feature's section.
These methods are added as Groovy extensions, so your IDE should be able to show them in auto-completion!
For example, you could do something like this within your Specification:
def setupSpec() {
reportHeader "<h2>Browser: ${driver.browser.name}</h2>"
}
def "My feature"() {
expect:
reportInfo "Some information I want to show in the report"
}spock-reports uses the slf4j-api for logging, so you can get logging information to investigate any issues you
may face with your Spock tests.
If your application does not have a slf4j implementation framework in the classpath, you may get this warning when running your tests:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
To get rid of the warning, add a dependency on a logging framework that implements the slf4j-api.
For example, to use slf4j-simple, add this line to your Gradle dependencies (or the equivalent XML in your Maven pom):
testCompile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.30'To configure the logging framework itself, please check the documentation of the framework you decide to use.
If you're using slf4j-simple, check this.
Most logging messages emitted by spock-reports use the DEBUG level, except when errors happen, in which case the
WARN level is used.
The base spock-reports's logger name is com.athaydes.spockframework.report.
Spock-reports can be configured via the Spock config file, a dedicated properties file or system properties.
All properties listed below are supported either way.
supported since version 1.5.0
All properties for spock-reports should be added in the spockReports block.
To set properties, use the following syntax:
spockReports {
set 'com.athaydes.spockframework.report.showCodeBlocks': true
set 'com.athaydes.spockframework.report.outputDir': 'target/spock-reports'
}Alternatively:
spockReports {
// set all properties at once
set( [ 'com.athaydes.spockframework.report.showCodeBlocks': true,
'com.athaydes.spockframework.report.outputDir': 'target/spock-reports' ] )
}If you prefer to use a properties file, the file should be located at the following location (relative to the classpath):
META-INF/services/com.athaydes.spockframework.report.IReportCreator.properties
If you use Grails, the above location will not work... the correct location depends on the Grails version you're using. See the following blog posts by @rdmueller for instructions:
If you use Gradle and prefer system properties, they should be configured on the test task, e.g.:
task('functionalTest', type: Test) {
systemProperty 'com.athaydes.spockframework.report.outputDir', 'build/reports/spock'
}If you use Maven and prefer system properties, they should be configured as
systemPropertyVariables in the configuration section
of the failsafe and surefire plugins.

com.athaydes.spockframework.report.template.TemplateReportCreator.enabled=trueBe aware that the outputDir property is relative to the working directory.
For Maven projects which use the defaults, you might want to change the outputDir to target/spock-reports.
If your build system can cache build outputs (to, for example, skip unnecessary build steps when in/out do not change),
register the outputDir as an output of the test task.
In Gradle, for example, this can be accomplished with the following declaration in your build.gradle file:
test {
// set to the same value as 'com.athaydes.spockframework.report.outputDir'
outputs.dir "$buildDir/spock-reports"
}The CSS properties above can be set to either of the following kinds of values:
- a classpath resource.
- a URL (the value will be used to call Java's
new URL(value).
If the value does not match a full URL starting with a protocol (eg. file:///usr/local/css/report.css),
the value will be treated as an absolute path to a classpath resource.
For example, if you set the value of a CSS property to my-css/test-report.css, the resource /my-css/test-report.css
will be looked up in all Jars and directories which are part of the classpath.
If you set the value to http://myhost.com/css/test-report.css, the resource at this URL will be read.
By default, the CSS resource will be inlined in the HTML report.
If you set the inlineCss property to false, then the CSS resource will be copied to the outputDir directory,
together with the HTML reports, with the following names:
feature-report.css(for thefeatureReportCssproperty).summary-report.css(for thesummaryReportCssproperty).
A link to the CSS resources with the above names will be added to the HTML file instead of inlining the CSS.
If you don't like the looks of the HTML report, or want your reports in a different text format, you can use the TemplateReportCreator to do that.
All you need to do to get started is provide a config file, or system properties, as explained above that
set the IReportCreator to com.athaydes.spockframework.report.template.TemplateReportCreator:
com.athaydes.spockframework.report.IReportCreator=com.athaydes.spockframework.report.template.TemplateReportCreator
# Set properties of the report creator
com.athaydes.spockframework.report.template.TemplateReportCreator.specTemplateFile=/templateReportCreator/spec-template.md
com.athaydes.spockframework.report.template.TemplateReportCreator.reportFileExtension=md
com.athaydes.spockframework.report.template.TemplateReportCreator.summaryTemplateFile=/templateReportCreator/summary-template.md
com.athaydes.spockframework.report.template.TemplateReportCreator.summaryFileName=summary.md
# Output directory (where the spock reports will be created) - relative to working directory
com.athaydes.spockframework.report.outputDir=build/spock-reports
# If set to true, hides blocks which do not have any description
com.athaydes.spockframework.report.hideEmptyBlocks=falseJust copy the above contents to a file at META-INF/services/com.athaydes.spockframework.report.IReportCreator.properties
relative to the classpath (eg. in src/test/resources for Maven users) and spock-reports will create a MD (mark-down)
report for your tests.
To provide your own template, change the location of the template files, the file extension you wish your reports to have, and the name for the summary report file, using the config file.
To get started with your own template, check the existing spec template file and the summary template.
You can see an example report created with the default spec template file here (this is actually used in the spock-reports tests).
The template report creator uses Groovy's GStringTemplateEngine to create reports based on a template file.
This template mechanism is very simple to use, but also very powerful, as you can write any code you want in the template file.
There are two templates you should provide:
- Spec report template: report for the run of a single Specification.
- Summary template: contains a summary of all Specifications that have been run during a JVM lifetime.
Here's the most basic Spec template you could imagine, which simply outputs the name of the Specification that ran:
This is a Report for ${utils.getSpecClassName(data)}
As you can see, you can use ${variable} to run actual code whose result will be printed in the report.
Another way to do this, is to use <% code %> blocks, as in the following example, which prints the name and
result of all features in a Specification:
<%
features.eachFeature { name, result, blocks, iterations, params ->
%>
Feature Name: $name
Result: $result
<%
}
%>
NOTE: before version 1.2.6,
eachFeatureused to be calledforEach. This had to be changed to avoid conflict with Java 8's method of the same name.
You probably noticed the use of some predefined variables in the template file code example. The available variables are:
data: an instance ofSpecDatacontaining the result of running a Specification.reportCreator: theTemplateReportCreatorinstance.fmt: an instance ofStringFormatHelper. It provides methods such asString toTimeDuration( timeInMs )andString escapeXml( String str ).utils: theUtilsclass offers many useful methods likeMap stats( SpecData data ), which returns statistics about the given Specification.features: as shown above, is an Object whoseeachFeaturemethod allows you to iterate over all the features of a Specification. When inside theeachFeatureclosure, you can access directly all members of the current feature (an instance ofFeatureInfo). So, for example, to get theTitleannotation of a feature, you can callutils.specAnnotation( data, spock.lang.Title ).
As the default template file shows, you can get statistics for the Specification easily with this code snippet:
<% def stats = utils.stats( data ) %>
Report statistics: $stats
The variable stats is a Map containing the following keys:
failures, errors, skipped, totalRuns, totalFeatures, passed, successRate, time
So, you can use it in your template like this:
Features: : ${stats.totalFeatures}
Total number of runs: ${stats.totalRuns}
Passed : ${stats.passed}
Number of failures..: ${stats.failures}
Number of errors....: ${stats.errors}
Number of ignored...: ${stats.skipped}
Success rate........: ${stats.successRate}
Total time (ms).....: ${stats.time}
Created on ${new Date()} by ${System.properties['user.name']}
The summary template has access to a single variable called data, which is a Map containing all the available data for all Specifications that were run.
For example, after running two Specifications named test.FirstSpec and test.SecondSpec,
the data Map could look like this:
[
'test.FirstSpec' : [ failures: 0, errors: 0, skipped: 2, totalRuns: 3, totalFeatures: 4, passed: 5, successRate: 0.1, time: 1000 ],
'test.SecondSpec': [ failures: 0, errors: 1, skipped: 3, totalRuns: 4, totalFeatures: 6, passed: 6, successRate: 0.2, time: 2000 ],
]You can then iterate over each Spec's data as follows:
<% data.each { name, map ->
def s = map.stats
%>| $name | ${s.totalRuns} | ${s.failures} | ${s.errors} | ${s.skipped} | ${s.successRate} | ${s.time} |
<% }
%>
Check the default summary template for a full example.
Please submit pull requests with bug fixes at any time!!
But if your Pull Request is about a new feature, please make sure to create an issue first so that we can all discuss whether it's a good idea and what's the best way to go about it.
Also, please notice that the master branch is supposed to contain only releases... the development branch
is called dev, so all PRs should be submitted against dev, not master.
Thank you.
