Any ideas on a cleaner way to write this? - run through a function with multiple steps; if any step fails, restart the function from the begining

Question

Basically there are 3 different functions for various "tests"; they each return "1" if the test passes and "0" on failure.  A "master" function calls these 3 functions in the desired order and keeps a counter
of tests that pass.  The counter has to be 1 to proceed to step 2, has to be 2 to proceed to step 3, and when it's 3 the loop closes.
This approach is giving the expected results, but I was wondering if anyone has ideas on a cleaner approach?  What I really wanted to accomplish was to have the 3 tests past in succession and to provide an overall pass and proceed to the next step;
and also to exit the function if any step fails rather than running through each step before trying again.  If the script were to for example loop through the 3 tests and wait until each one passes, tests 1 and 2 might pass, but then 3 might fail
a few times and finally pass before the script exits.  I did not want to allow for that scenario to count as an overall pass.
Function Test1 {
If PASS Return 1
If FAIL Return 0
Function Test2 {
If PASS Return 1
If FAIL Return 0
Function Test3 {
If PASS Return 1
If FAIL Return 0
Function TestAll
[int]$counter = 0
$Check1 = Test1
If ($check1 -eq 1) {$counter++}
If ($counter -lt 1) {Exit}
Start-Sleep -s 15
$check2 = Test2
If ($check2 -eq 1) {$counter++}
If ($counter -lt 2) {Exit}
Start-Sleep -s 15
$check3 = Test3
If ($check3 -eq 1) {$counter++}
If ($counter -lt 3) {Exit}
Return $counter
Do {$STATUSCOUNT = TestAll}
While ($STATUSCOUNT -lt "3")

This is cleaner:
Function Test1 {
If PASS Return 1
If FAIL Return 0
Function Test2 {
If PASS Return 1
If FAIL Return 0
Function Test3 {
If PASS Return 1
If FAIL Return 0
Function TestAll{
while($true){
while($true){
$counter=0
if(($counter+=Test1) -ne 1){break}
if(($counter+=Test2) -ne 2){break}
if(($counter+=Test2) -ne 3){break}
return
Write-Host ('try again' + $counter) -fore
TestAll
Of course all of your test functions have syntax errors.
