You can escape the slashes, like sed -e 's/"@base_url = "http:\/\/dmstaffing-stage.herokuapp.com\/"/d'. This jungle of /\/\//\// is a symptom of what is called LTS (Leaning Toothpick Syndrome). The best way around this is to just use another delimiter, like ; in your case, or whatever other non-alphanumeric character tickles your fancy today (and isn't ...

As mentioned, use other separator or escape the slashes. Your last try misses escape of last slash.
And as pointed out by @StephaneChazelas, escape dot's as well.
And, including @terdon if sed is not needed; grep -Fxv, where -F is fixed string, not regex, would be an option. -x makes sure it matches whole lines. -v inverts.
A simple (very simple) ...

The slashes in the regex are messing up with sed's delimiters.
But you can use different delimiters than the slash. For example:
sed 's#@base_url = "http://dmstaffing-stage.herokuapp.com/"##' xx

Try using another separator:
sed 's|@base_url = "http://dmstaffing-stage.herokuapp.com/"||' xx

Portably:
sed -e 's/.*/ & /' -e :1 -e 's/ test3 / /g;t1' -e 's/^ //;s/ $//'
That is:
first add a space at the beginning and end of the line, to not have to consider test3 at the beginning and end specially,
replace test3 enclosed in spaces with a single space,
repeat the process as long as there are substitutions (to cover the test3 test3 cases).

I'd look for test3 wrapped with a space on either side, \s, given your example rather than try and use the word boundary notation.
For example
$ echo "test3.legacy test4.legacy test3 test3.kami" | sed 's/\stest3\s/ /g'
test3.legacy test4.legacy test3.kami
The above looks for space test3 space and replaces this with just a space.
NOTE: This won't handle ...

Is this what you want?
$ sed 's/\(^\| \)test3\( \|$\)/\1/g' file
test3.legacy test4.legacy test3.kami
This say
substitute
(^ start of line OR space)
test3
(space OR end of line)
with match 1 (AKA space or start of line)
Update:
And as so elegantly put by the good @Stephane Chazelas this would not take care of certain cases. Also emphasize ...

find . -type f -exec sed -r -i "/textword/d" {} +
Remember that the search text is interpreted as a regexp by sed (with the -r option), so it might need escaping.
Use sed -i.backup to backup original files as <filename>.backup.

With GNU find and sed you could:
find . -type f -print0 | xargs -0 sed -i '/^FIND$/d'
