• Minecraft| Install Java on Apple Mac OS X Yosemite 10.10 for Minecraft 1.8. Can’t run Minecraft 1.8 on the Apple Mac OS X Yosemite operating system? This video can help you out. Apple provides a link in Yosemite to install Java 6 to allow Minecraft 1.8 to work. The Apple web site links to Java 6, specifically 1.6.0_65, a 64 bit version.
• Oracle's JDK 7 Update 67.pkg will not install with Apple's Installer.app probably not an issue with Yosemite. I doubt that Oracle will rush to update an installer for 7 when Version 8 Update 20 is a (greater) recommended version. The first.jnlp file that I tested worked with Java 8. Environment: Mashemite:~ grahamperrin$ java -version.

• Platform(s): Mac OS X
• Java version(s): 7.0, 8.0

I need to test a web application with JRE 6. I am using a Mac with OS X 10.10 and Java 7 for development. How can I install JRE 6 next to Java 7 on this Mac?

This previous answer does not yet account for the fact (also mentioned in a comment) that Apple's download link by now points to a .pkg (Java for OS X 2014-001) file. Without further knowledge I hasten to install it, for it may overwrite my current Java 7 setup (and may no longer contain JRE 6 in the first place).

JavaForOSX2014-001.dmg contains Java for Mac OS X (1.6.0_65-b14-462). It will be installed to /System/Library/Java and /System/Library/Frameworks while Oracle Java is located at /Library/Java. No file will be overwritten.
To avoid any trouble (especially with your $JAVA_HOME/$PATH) consider setting up a Mac OS X VM in VMWare, Parallels or VirtualBox with JRE6 only.

As noted by @klanomath 'No file will be overwritten': You can have multiple JDK's installed but only one JRE. But each JDK also comes with a JRE.

Apple's Java integration with OS X provides /usr/libexec/java_home that can help you keep the JDK situation straight. That selects among the JDK's and their associated JRE found in /Library/Java/JavaVirtualMachines. See the man java_home page.

However there is no equivalent capability to select among versions of the JRE accessed via /Library/Internet Plug-ins/http://support.apple.com/en-us/HT202643 provides the only 'official' way to select among those, which requires terminal savvy with sudo and symbolic links. Since you are a developer testing web apps one assumes that will suffice, but not something mere mortals want to mess around with.
