Cannot Find Assert.Fail And Assert.Pass Or Equivalent


Answer :

The documentation includes a comparison chart including this:

Fail - xUnit.net alternative: Assert.True(false, "message")

(It doesn't show Assert.Pass, and I've never used that myself, but I suspect the alternative is just to return from the test. Of course that doesn't help if you want to throw it in a nested method call. My suspicion is that it's not very frequently used in NUnit, hence its absence in the comparison chart.)


An alternative to Assert.Fail("messsage") suggested by xUnit docs

xUnit.net alternative: Assert.True(false, "message")

has a downside – its output is

message  Expected: True Actual:   False

To get rid of

Expected: True Actual:   False

don't call Assert.True(false, "message") throw Xunit.Sdk.XunitException instead.
For example, create a helper method similar to this:

public static class MyAssert {     public static void Fail(string message)         => throw new Xunit.Sdk.XunitException(message); }

Just throw an exception to satisfy both requirements (exiting a nested loop and an alternative to the missing Assert.Fail method). Only issue is there is no decent base exception (e.g. TestException) to use in order to avoid getting warnings about using the base Exception class, so something more directed like an InvalidOperationException is probably a good choice.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
