| <h2>Reading File and Clipboard Content</h2> |
| <small>Aug, 12, 2015 by Ulyana Skorokhodova</small> </header> |
| <div> |
| |
| <h3>Reading file content</h3> |
| |
| Until recently there was a few ways to get a file content:<br> |
| |
| <ul> |
| <li>Opening file editor in GUI and getting it's <i>text</i> property |
| <li>Using <a href="https://ci.eclipse.org/rcptt/job/master/lastSuccessfulBuild/artifact/releng/doc/target/doc/ecl/index.html#read-csv-file"><b>read-csv-file</b></a> and <a href="https://ci.eclipse.org/rcptt/job/master/lastSuccessfulBuild/artifact/releng/doc/target/doc/ecl/index.html#read-lines"><b>read-lines</b></a> commands</li> |
| </ul> |
| |
| Both ways have obvious restrictions making their usage not very user-friendly, so we decided to implement a new <a href="https://ci.eclipse.org/rcptt/job/master/lastSuccessfulBuild/artifact/releng/doc/target/doc/ecl/index.html#read-file"><b>read-file</b></a> ECL command to get a file content.<br><!-- break --> |
| It takes a file <i><b>uri</b></i> as an argument and returns a String content of a file: |
| |
| <pre ><code class="language-ecl">​read-file -uri "file:/Users/Ulik_MacAir/MyProject/File.txt" | log |
| </code></pre> |
| |
| |
| You can use either absolute or relative uri (use workspace:/ to point to your AUT workspace): |
| |
| <pre ><code class="language-ecl">​read-file -uri "workspace:/MyProject/File.txt" | log |
| </code></pre> |
| |
| |
| Usually you need to get a file content for further verifications. Lat's say we need to compare a content of two files. <br> |
| So here what our test will look like: |
| |
| <pre ><code class="language-ecl">​read-file -uri "workspace:/MyProject/File.txt" | equals [read-file -uri "workspace:/MyProject/Copy.txt"] | verify-true |
| </code></pre> |
| |
| <br> |
| <div class="panel panel-warning"> |
| <div class="panel-heading"> |
| What may go wrong? |
| </div> |
| <div class="panel-body"> |
| <i><b>Failed to read</b> /MyProject/Unexisting.txt at read-file (/ReadFile/Test.test:3)</i> - means that there is <b>no such file</b>. <br> |
| <i><b>Failed to resolve</b> /MyProject/Copy.txt at read-file (/ReadFile/Test.test:3)</i> - means that file uri is in <b>wrong format</b>. Most likely you forgot to add <b>file:/</b> to a file path. |
| </div> |
| </div> |
| |
| <h3>Operating with a Clipboard</h3> |
| |
| Clipboard is always used to check a correct work of Copy/Paste actions. <br> |
| RCPTT can now operate with a clipboard directly using <b><a href="https://ci.eclipse.org/rcptt/job/master/lastSuccessfulBuild/artifact/releng/doc/target/doc/ecl/index.html#to-clipboard">to-clipboard</a></b> and <b><a href="https://ci.eclipse.org/rcptt/job/master/lastSuccessfulBuild/artifact/releng/doc/target/doc/ecl/index.html#from-clipboard">from-clipboard</a></b> commands.<br> |
| |
| So if you need to paste something you don't need to do coping actions before. You can do like: |
| |
| <pre ><code class="language-ecl">​to-clipboard MyClipboardContent |
| |
| with [get-editor "File.txt" | get-text-viewer] { |
| get-menu Paste | click |
| } |
| </code></pre> |
| |
| |
| Likewise, if you need to check that copying works correctly, you don't need to do pasting afterwards. You may simply check a clipboard content right from ECL script: |
| |
| <pre ><code class="language-ecl">​get-view "Test Explorer" | get-tree | select MyProject | get-menu Copy | click |
| |
| from-clipboard | equals MyProject | verify-true |
| </code></pre> |
| |
| <br> |
| <div class="panel panel-info"> |
| <div class="panel-heading"> |
| Information |
| </div> |
| <div class="panel-body"> |
| If you need to put a big text into a clipboard it may be more convenient to use ECL Script Context for this purpose (just to make your test script more readable and laconic). |
| Please note that Workbench Context clears clipboard, so make sure that your ECL Script Context goes after a Workbench one. |
